The Obscure Transformer Website was originally founded by Andrew Sorohan, an Australian Transformers fan who goes by the nickname Jhiaxus. The current site is maintained by Matt Karpowich, otherwise known in the Transformers fan community as Monzo. He can be reached at firstname.lastname@example.org.
Jon and Karl Hartman are longtime members of the Transformers fandom and the founders of BotCon, the official Transformers convention. They provided their collection of Toy Fair catalog pages to Matt for the purposes of scanning.
The mechanical heart watermark used on the Toy Fair images was drawn and colored by David Henion, aka strangefour.
