Bob Kane sketched and signed this card. I bought several copies (getting rid of the lesser grades) of a small grouping of Laird, Bob Kane and Schultz sketches with the respective authors’ signatures. I have a coa from Sportsfanatics where I obtained the collection from. I am not an autograph verifier so I cannot provide any other authenticity of these which is why I am listing lower than similar authenticated items on ebay. That said, these are being sold as is. If you verify their authenticity then awesome! If these come back unauthentic then I am sorry but buyer beware.
