Yes there was indeed a time when one design would pay for the set. In fact, I have been creating and selling hot sets since 1986 to this very day, I understand the market trends and have helped shaped the contemporary tribal evolution in New Zealand in the 1990's. There is a gamble buying flash especially when there is no demand. You are RIGHT on the mark David.
@Ursula, I like what you said that it would be much better to invest in an artists talent for painting than buy his flash which would make your home look like the wallpaper of a tattoo parlour. I guess collectors see it as a valuable and important part of the tattoo evolution history that should be preserved the same way stamp collectors think. I personally dont decorate my living room with flash, I would rather leave copies on the walls of my work studio and the originals sealed and locked. Maybe its about choice as an investment for business or as a collectors item for non tattooers.
Oh, by the way hello everyone
