These would look fantastic restored and framed!  They are very colorful and show great patina.

A couple of the posters have a show date that was previously attached (probably with poster glue) onto the main poster image.

These are pretty old (unknown year), and slightly fragile - but would respond well to restoration and/or linenbacking.  They are certainly interesting!  They would make great decoration for an AirBNB, restaurant, office, or home.
