Awesome! I'm glad everybodies chiming in about this project. I'm not going to be able to answer all the questions but I'll try and give some useful info.
Q: Holy Crap Jackson why are there so many version of these stinking decks, you sure are a greedy money grabber! (No one said it like that, but that is the way I hear it.

)
A: First off there will be no Bicycle Branded Decks in this project. There are a few reasons why I have more than one edition in all of my projects. When I'm doing a project I go through so many concepts and ideas that more than one may jump out at me and really catch my interest. The Holmes project is just the same. I wanted to try a style completely different than the Fed engraving style thus that is what you see on the Holmes and Moriarty editions. However it is the engraving illustrations (just like with the Fed) that made me fall in love with the Sherlock Holmes story in the first place.
I'm am also extremely ADD so I do not have the focus to shelve an idea and say "I will just release that at another time" I have to continually change my work and concepts simply to find joy and interest in what I'm doing. When I do come out with different variations I do so trying to create meaningful differences to make it make since. That is why I am almost doubling my workload and creating 2 unique court sets (two of which are the same art but with different thematic color approaches) So in all honesty 3 court sets.
I also promised my self that I would never just hue shift a back design and call it another version. I own atleast Six Smoke and Mirrors and no one seems to care about that much. Sure they release them over time so it may be easier on the wallet but when I reales them all at once I have strive for great designs and meaningful differences to win your purchase.
Thoughts on Collecting and the "I have to buy everything mentality"
I was recently in Las Vegas for the 52+ Joker convention and I spent almost 4 days with Paul Carpenter and Alex Chin. We talked about nothing but card design and where we hoped that the industry and collecting market would go. Alex Chin gave an incredible presentation about "Focusing your Collection" I think most all new collectors of any product or market start out with an energetic approach to buy everything that come out. But after years of collecting they quickly find that most of their purchases don't really do anything to add to their collection. Alex also spoke about how as a collector you have to narrow your scope of what you are looking for. You can already see this with the Bike crew that only buy bike decks. I think that is great. Buying everything right out of the gate isn't bad it is what everybody does in the beginning. It is what I did as well.
I met so many wonderful people / collectors their that have been collecting playing cards for over 50 years. 10 out 10 of those people told me I don't buy decks anymore. Do these people have huge collections? Some do, some don't. But what most of them DO have is incredibly rich collections that are absolutely focused and beautiful. It was also a huge thing for me that these people would buy one or two of my decks. (Side note none of these people buy bricks)
As you can clearly see with the Sherlock designs people are already gravitating to the baker street edition, but what you may not realize is that only the newer collectors gravitate towards the Baker Street Edition. All of the old collectors I met at the convention gravitated toward the stylized ones.
Then you have to think about the audience base that the Holmes stories have. Card collectors are now only a small number of people I am trying to connect with compared to the fans of a story set that is more than 100 years old.
Q: Why the one way back design?
A: I have No one way back designs in this project. I have already found that you guys crucify any one who does

Which is another topic all together that I won't touch at this point. Slapping the back design on the box isn't something I think that everyone has to abide by, it gives the designer another blank canvas to create something new.
Here are some details to clarify what I will be offering:
Backer Street Edition
Limited Edition Baker Street
Holmes Edition
Moriarty Edition
I have plans to create a limited edition Holmes & Moriarty set, but I'm trying some new things with tuck design and it is not coming together as much as I hoped it would so I may punt on the idea and only offer the four decks listed above.
I think as collectors we should buy only what really speaks to us. Sure I would love for any one to buy a brick of everything I created but what would that serve me in the long run. I have chosen to make my living designing cards so I would hope that you are buying my cards because they speak to you and that you enjoy the art, not just because you have to buy one of everything. I would go as far to say if you don't like my Holmes designs don't buy them. If more people chose not to buy stuff now and then the quality of design would rise even faster. People are slowly trending that way and I think it is a great thing.
More specifically (as an example) if one of the biggest things you look for in a design is "Small Borders" the best way for you to start seeing more designs with small borders is to support and buy decks that have small borders. I think it is funny when people are like "Come on those borders are huge! I want thinner borders!" but at the same time will burn someone at the stake if they don't use USPC to print the decks. If you want small borders you may have to branch out a bit or people like USPC will never innovate to appease the crowd because they don't have to. I have some pre 1900 USPC decks that Have NO borders at all, the pips and idicies go all the way to the edge. If you want to see a change in the market you have to make the change by speaking with you wallet.
