bubbles/adhesive/oldposterbook

[Robespierre]

i framed some old Vogue covers. First I used Economount (nonrepositionable adhesive but reputed to be weaker than Jac paper). Then I used Gudy mount (Nieschen, repositionable adhesive). In the first bubbles appeared but only after a couple of weeks. In the latter bubbles appeared sooner. I seem to recall mention made in this forum of humidity playing a part and the Vogue covers were effectively, thick (old) paper. Is there a general principle here. For example, never mount down unless absolutely necessary?

Yes

Robespierre,

Unfortunately, I think that you have a number of things to keep in mind here:
1)The age of the artwork.
2)The value of the artwork.
3)Possible contaminates in the artwork itself.
4)Wether or not you can replace the artwork.

If any of these thing make you stop and thing a moment... don't do anything that is not completely reversible.

Good Luck.

Thanks for the advice. As a relative newcomer, I believed the supplier's advice on his product although he mentioned a horror story of an original signed poster from "Hello Dolly" signed by the cast and mounted in a hot press whereupon all the signatures ran together....

Robespierre:
Never mount unless absolutely necessary. In fact, I'll never let adhesive touch art unless necessary...don't let it be a restorer's nightmare in the future. If I can, I like to use acid free acetate corners on anything that requires a conservation mount. Good luck!
