A 1987 bookmark featuring Wonder Woman, printed as part of a DC-backed literacy campaign. I would have guessed that Dick Giordano was at the very least the inker of the illustration, although far more informed folks assure me it’s the work of Jose Luis Garcia-Lopez. (It’s hard to imagine the no-longer-so-Nu52 version of the character fronting a comparitive initiative, or, indeed, being able to convincingly hold such a confident, winning smile.)
update: Sean Kleefeld has diligently identified the art as being “a García-López stock image with a bad redraw on the arm to include the book” - see here. My thanks to his splendid self.
