The Illustrated Harlan Ellison - Please Help!

[pie-migration]

I recently obtained a signed copy of the 1978 edition of "The Illustrated Harlan Ellison". I am trying to find out what it is worth.

I got one of these when it came out. Not aware it's gone up in value, although the glasses are detached in mine and the glue has dried a lot, so a fair few pages are loose. If your glasses are still attached, then try and get some others to look at the 3D, which is about the only good thing in the book.
