There are very few things I'll keep from a production. Typically the program, a postcard, maybe a picture or two, that's it. I almost never keep props. The above is an exception. When I produced "The Information She Carried," the set was designed by Kley Gilbuena. Since the play is about a conspiracy theorist, he constructed nearly everything with file cabinets and papers. It was fantastic!
One of my favorite things he created was a pillowcase, stuffed with papers, to sit at the head of a file cabinet bed. The pillowcase was covered with conspiracy theory scrawlings and audience members would want to take a look at it after the show. Most props don't interest me, but this one I had to keep.
