Gregory,
Here's what you can do, either have "sold" on both of these and sell "new" versions, if somebody wanted these, exactly the same size, or explain these are you prints for art shows and not to be sold at the shows, unless the people want to leave with these.
If you have the print itself, a "retoucher' can fix these, as you can if you practice. But framed and behind glass I don't think this is an issue.
