When updating the commodities I noticed that I didn't have the original black tradecard back, only the modified red and blue ones. I have tried to re-create the black one using the blue, but it won't be as good as the original.
If anyone has it, preferably in psd format, but png/gif is better than nothing, please email it to me (jon@severinsson.net). Thanks in advance.

I found an old jpeg I cleaned up and put as a png at http://jon.severinsson.net/civproject/tradecards/
I'm still looking for an psd file, though I beleve that one went MIA 2003...

Thanks to Pureblade I got my hands on the bmp originally used to generate the jpeg.
So, a png with 100% original quality is now available at jon.severinsson.net/civproject/tradecards.
Please replace any of my previous attempts at a black tradecard back with it.
If anyone has the original, layered, psd of the tradecard back I'm still interested, but unless we have to change something the current solution is adequate.
