830. Marilyn Monroe footprints and signature in test slab for Grauman's Theater forecourt. Cast cement slab measuring 17 x 22" and weighing 23 lbs, which was preserved by an employee of Grauman's Chinese Theater in 1953 after a nervous Marilyn was allowed to "practice" to familiarize herself with the actual process of working with the wet cement, because the whole world would be watching her sign and print the finished slab. This "practice" process is known to have occurred with other stars as well, as the same artifact for Joan Crawford's practice-run was sold in her estate auction. It is interesting to note that Marilyn practiced with bare feet, as only 2 adult stars exist barefoot in the forecourt, Harpo Marx and Sean Connery. Accompanied by a COA detailing this unusual artifact's history.
