I recently purchased a copy of a 1991 1st edition of Greenberg's Guide to Varney Trains. as I was skimming through the pages I found that the book had 8 pages of over print on them. The over print was of Star Trek collectables. I have gone to both Greenberg Train shows (who at one time owned Greenberg publishing and then was refered to go to Kamlback. In both cases no one could give me an anser on weather or not some of the books when pritned had this issue. A freind of mind has the same book with no issues. i am trying to find out if anyone has any inforamtion on this, thanks.
