New Guy! I need help with 1958 Topps Error/Variation

[jbrown]

Hey guys, I'm new here. My name is Justin. I found this card in a collection I recently purchased and can't find any info on it. Heck, I can't even find another player with the same printing error. There should be at least an entire sheet worth of cards with this mistake but I can't track any down. Basically my question is, could this possibly be the only one(Randy Jackson) like this and is there much value for an error like this? Thanks for your help!!

I think they are either misprints or proof runs. Here is something similar from 1957 and how PSA dealt with same--Herzog and DeMaestri
