Notes:
Information from Amazon. They give the first Bantam Pathfinder edition's year and month but use this one's cover scan. Judging by the catalog number, this edition is from 1970-71. Bama's signature is visible on the reuse of the art on the 2012 Centipede Press edition of The Strange Case of Dr. Jekyll and Mr. Hyde (here it's hidden by the title).
