Another of my favorite ads, from 1972 DC titles, in the last of the 52-page issues. I'm hard pressed to name another ad that made me want to purchase a book more.
When I finally got a copy in 1995, I was inevitably disappointed. But that wraparound cover is one of the nicest pages Kirby ever produced. The disappointment is in that it primarily contains Golden Age/1950's Kirby material, very little 1960's/1970's material the cover would be representative of.

The later 1978 Kirby MASTERWORKS book in the same 11" X 14" black and white format has a far superior selection of Kirby pages. I believe they were both published by Mark Evanier and Steve Sherman.
