I had a similar project. There were two wine bottles and four labels that had been removed from other bottles, but no wine glasses. I mounted the bottles by using a small glass shelf and a wide clear film strap, as already described.
The labels were mounted by wrapping each one in clear film, and then I elevated them off the background surface at different levels using undersized layers of foam center board. According to the customer's wishes, the label for the most expensive wine was elevated nearer the glass, which made it more prominent in the design.
If I were doing the same job today, I'd probably wrap each label in Stabiltex, using a carefully sized 4-ply backer. As with the clear film mounts, no glue would touch the labels.
I don't like to use adhesives in direct contact for these reasons:
1. Adhesive bonds are prone to failure in one of three different ways.
2. Adhesives leave permanent residues.
