Have done this set 4 ways. White backs, gray backs, undeckled ( mixed backs) and complete set on 2 uncut sheets. I had to look a long time for the last white back I needed, Carlton Fisk. Got it from Steve Werley ( RIP) who helped me with a lot of off beat Topps stuff over the years ( at a price
)
Had not noticed the tacky issue Dave. It is one of the few issues where I ended up with a lot of graded cards because that is the way I found them, and never broke them out....as I am usually want to do.
In addition to having 4 Gibsons in the formats listed above I ended up with a 5th one, which I assumed was a fake when I got it since none of my other undeckled cards have the deckling on them
