Jon, just to make things more confusing, the GCD lists the Tor books as 2A/B being the two different sized books with the same interiors and 2C as being the next issue (what you have called 2B). Blame St John for numbering them all the same.
I don't know how much extra trouble it was to do the flat black-and-white versions of the books but they look great! You'd never know there was a double image. I'll keep both in case I lose my glasses sometime. Btw, are we seeing the red or blue plates? Kudos!
