This daybill was previously framed and had the top border glued down to masonite. Having removed it with some un-du and a blade, I now find the glue is still tacky. The paper is also very brittle and chips easily.
Not super high value, but there aren't many copies around and I would like to preserve it as best I can for the new owner.
Should I use archival tape on the top to reinforce and cover the glue?
I realise backing is the answer, but that's not in my budget.
Thanks in advance.
