Probably the largest cylindrical hologram ever made, and ranking up there with the largest holograms as far as surface area goes, are those recorded by Juris Upatnieks, Emmett Leith, C.D. Leonard, and E,J. Martilla from 1973 to 1975 in Ann Arbor, Michigan. They were big enough to contain a guitar as illustrated below, from an article in holosphere, October 1978.

Holo-historians should wonder where these objects currently reside!
