Hello,
I purchased a Rob Gronkowski 16x20 from someone who purchased it from eBay originally. It came with a COA from YourSportsMemorabiliaStore but I cannot find a hologram lookup on their website. I had to go back a few years but there was one picture of him doing a signing at what appeared to be YourSportsMemorabiliaStore. I think it looks similar to other examples I’ve seen that are legit. Appears to be signed in silver sharpie or paint pen.
Any help would be appreciated, and also if that is a reputable dealer going forward.
