Unnecessary worries

I was thinking about making shirts for us local Sherlockians, since it is a key anniversary for a couple of the scions in St. Louis.

I was thinking about getting some artwork made that looks like a parody of the Cardinals logo (http://wugange.com/st-louis-cardinals-logo-2-birds-25655-hd-wallpapers.html) but the birds would be dressed as Holmes and Watson. Instead of the bat, it would be a Victorian walking stick that the birds would be perched on. The letters beneath would say "Sherlock Holmes" or something of that nature. 
 The shirts would be jersey style, and then on the back we could have whatever you want on it. I think it would be neat if the letters on the back had the affiliated scion and then the number of years in St. Louis, but that can be whatever one wants.

 To recoup the cost of the artwork, the shirts would be sold for ~$20-30 per shirt, depending on how many people decide to order one.

 I've attached a rough sketch of what I'd like it to look like. What do you think? Maybe I could have a couple of versions made? one for just St. Louis people and one for everyone else?


What do you think, dear reader?
