I've searched the forum (and the auto forum) for opinions on GTSM (GT Sports Marketing) authentication, but haven't really found what I'm looking for. All the things that I've found had something to do with attending one of their shows.
My question is if an autographed item has a GTSM holo on it is that legit? Are they like PSA/DNA, JSA, GAI, Mounted Memories, Tri-Star, etc?? -- Or are some of those that I listed not even legit?
Just curious if it's a solid LOA or if it should be questioned?
Thanks!
