removing glued poster off of mountboard

[dave1]

I have a client who has brought in A vintage film poster that has been glued in multiple spots around the edges that has caused the poster to ripple.
Any suggestions on how to remove the poster from the mount board without damaging it?

Hello,

I would not attempt to do this yourself to a vintage poster. A paper conservator would be your best bet. Once the glue is removed I would be recommending a linen backing to keep the poster in good shape for the future. I think in the film poster collecting world this is an acceptable form of preservation without affecting the value... I think.

A quick googles brings up this https://www.linen-backing.co.uk/index.html which is not far from yourself.

As David said

Don't even attempt to take it off, especially if it's an original vintage poster

Find a local paper conservator, build up a business relationship with them, I have been recommending the same one for the last 29 years, he also sends customers to me as well

You've probably got no idea what it has been stuck down with and even less idea of the state of the paper in the poster, or what happens if the paper gets wet. That all adds up to a rather nasty can of worms, that you could very easily wish you had not opened.

Let some one who is properly trained and experienced solve the problem for you and start a working relationship with your local restorer, it will add to your reputation and give you some one to turn to for unbiased advice when you need it.

Most customers will love it, if you can arrange for your expert restorer to call in and give his opinion and his price to do the job.
