Some time last year I found an excellent website owned by Dan called "Dan's Fantasy Art Collection" and on his website he had a similar "Study" by Mike Hinge but with a more evolved picture that you can see "here" (21 pictures down). Dan told me that this work was commissioned to illustrate "Redeemer"- a story by Gregory Benford in Analog Magazine April 1979, but carries the notation on the back "rejected/unpublished".
The published "Redeemer" illustration can be seen below.
In the last few weeks through the grapevine I was contacted by Matt (a friend of Mike Hinge). Due to a house move he thought the time had come to let go of some Mike Hinge - tear sheets, photocopies, books and printers proofs that Mike had given him over the years. The long treasure items have now safely arrived with me and I now plan to share all the pieces here...first off... Look familiar?
Mike Hinge - A3 size black and white photocopy, date unknown.
Mike Hinge - A4 colour photocopy and acrylic paint (the title Weird Tales has been hand painted).
Date: Summer 1993?
Thanks Dan, Thanks Matt.
