Regarding #1

I was about to call it “Saint Bonaventure at the 3C Diner”, but backed off, because that really is a riddle, to which only I know the answer. So, as a riddle it properly belongs on the reverse, where it will document what I was thinking at breakfast one spring day in 1979. If you are the first person to come extremely close to figuring it out, then I will send you a signed proof of the obverse image.
