$5 in my totally rad squeeze coin purse. At a book fair in school, I purchased 2 books. For timing reference, there are Smurfette stamps on the inner covers!
This was one of my favorite pages:
At a convention several years ago, a former TSR artist and employee had that original piece. And I had a ... moment.
The artist stated "My wife feels I should sell you the art. You seem really taken by it."
So several decades after purchasing the book, at a convention in Lake Geneva celebrating the life and works of Gary Gygax, I became the curator of this original piece by Harry Quinn!
