Hi Donna,
Thank you very much. At least understanding what it is, helps a lot, and it explains the tape residue that was left where parts have peeled off. I'll look into the possibility of lamination.
Thanks again,
Susan

Hello Susan,
I was a cartographer in the 1970's. This looks like an adhesive line tape we used at the time.
My personal reaction: adding glue underneath may not place the tape back where it was originally. I don't have a background in preservation... Encapsulation wouldn't necessarily keep the tape from displacing more. Might a process such as lamination keep the tape in place? It would create a stiff product, with different qualities than the original, but the tape would stay in place.
Yours,
Donna

Good Afternoon from Vancouver Island, BC. We are working with a map from the 1970's Mylar maps that have linework that is very fragile and falling off. We are unsure of what material was used originally, and would like to know what we could potentially use to glue the linework back on. I'm not sure if images will come through here on the listserv, but I am including them just in case. If you have any suggestions on how to proceed that would be very helpful.
