I have a few 1960s/70s cards signed with blue and black Sharpies that are apparently TTM secretarials or such (signed in the late 70s/early 80s). Since the cards are basically ruined to begin with, I'm wondering if anyone has experience in soaking off the signatures in order to make them 'whole' again? The writing is on front, so it sits upon the gloss, which would seem to be a good thing, but who knows if this type of ink fuses to said gloss. At least one of the blues has turned lighter and purplish over time, so it doesn't seem to be overly permanent?
I know the most likely answer is I just have to try it for myself and see, but I'm hoping someone has some experience-based insight they can offer.
Thanks!
