'3M Spraymount' aerosol glue in a 400ml can, used throughout the graphics industry for sticking (mounting) paper,
expensive to buy but a can lasts years.
I have used hundreds of cans throughout my working life sticking paper patches on old fashioned, pre computer artwork,
applied lightly it will not wrinkle plans or photo copies etc.
Sticks photo copies of plans to plywood perfectly for band sawing etc, leaving little glue residue,
but any residue is easily removed with Ronsonol liquid lighter fluid in a spout type tin,
evapourates away without staining or marking, wonderful stuff but pricey.
