Since I have an old style home theatre, I have all my posters displayed in its lobby, foyer and throughout the house.
I mainly collect pre-1955 material, specializing in the gorgeous lithography and graphics of the 1930s and 40s.
I always keep an eye out for frames at garage and estate sales, since new ones are expensive.
For my larger or unusual size posters, such as 14x36 inserts or 41x80 three sheets, I build my own frames--very easy if you have a mitre saw and basic carpentry skills.
Posters don't have to be expensive, if you shop for the lower priced lesser known titles on eBay, etc.
I've branched out to lobby cards, window cards, small da-glo banners, inserts, one sheets, three sheets and 24x72 marquee banners, which I rotate displaying. I do sell off extra material occasionally to keep the money recycling in the hobby.
