Review on Clear Wall Protector Contact Paper - Multipurpose Self Adhesive Removable Vinyl Film: Transparent, Waterproof, Heat Resistant & Oil Proof- Ideal for Kitchen Backsplash, Furniture, Doors, and Pets! by Whitney Bailey

I might be more careful but you may want to test this on an artwork as your adhesion (or the finish of the artwork) may vary. I just cleaned and sprayed with polythene but the base adhesion was poor. I had to suffer with a huge blister and not completely lose the surface when it came off. I ended up using scissors to cut and plant the bubble. I post pictures for editing. As advertised - thicker, better and more expensive - although I'd go straight for a regular roll and save a buck. ALSO - for most uses - the smaller roll is easier to fit and you can pretty easily double the width and make it look like a giant size out of cheaper material.
