I was on eBay and the guy is selling a JK Rowling‘s signed Harry Potter and the chamber of secrets you can’t tell me if it’s authentic or not but he said he got it from an estate There’s no hologram or COA I’m just not really good with sign books I’m usually collecting of sports memorabilia
Yea I noticed that also it’s hard to tell because her signature is so easily copied and I found another one but I can’t tell if the coa is real it checks out on the site but it’s on a 8 x 10 paper idk if it’s something they do
