I’ve added a copy of the 4th paperback printing of Gryphon in Glory, published in 1984. It’s nearly identical to the 1983 1st printing, except that the 1st printing has a curved banner reading "First Paperback Publication" and the 4th printing’s banner reads "Science Fiction Adventure". Still looking for a 1986 printing, in which the colors of the banner font and Norton’s name are switched from the earlier versions.
