Default When did Blue Sharpie Become Common?
Quick question for those of you who have been at this longer than I have. Can you comment regarding when blue Sharpies became commonly used for autographs? I am looking at an unauthenticated card for a player who died in 1991, and it is signed with a blue Sharpie. If there is nothing usual about a autographed card from the late 80s signed that way, I'll be doing more due diligence, but don't want to waste any more effort if this is unusual.

Thanks in advance.
