There are three versions.The first have plain covers and there are only about five pairs in existence.The second have the drawn covers, drawn at DC itself, and are legitimate, made by some fans who worked within DC and there were a limited set of exactly fifty made. I have one of these. Paul Sassienie picked it up for me many years ago in San Diego.The third are bootlegs taken off the second. These look quite similar but the printing is nowhere near as clear and sharp. They are in the light blue shiny covers with the black plastic binding, like a facsimile of the real ones.The bootlegs do often come up on e-Bay if you look for them. But even the bootlegs aren't all that common. Someone went to a lot of trouble to make them look convincing.
