I'm not sure of the signature authenticity, help please. The Steiner cert has a sticker, however the photo does not so I'm believing this is a forgery. The seller has numerous of these listed and currently has nothing but McGwire signature's.
Wow! Thank you. I know we should determine authenticity of each signature on it's own merit, however I failed to follow that rule and because the Steiner cert seems fishy I assumed it was fake even though I thought it was close enough for me to ask for opinions. Thanks, again.
