Housed in the old Maxfactor building and full of some great memorabilia. Two make up rooms still exist, one of which was used by Marilyn Monroe herself. The museum is also home to one of the 2 remaining pairs of ruby slippers worn by Judy Garland in the Wizard of Oz (when I was there at least!)
Other than that there is history of the Oscars and Hollywood walk of fame as well as costumes and a Chevrolet used by Marilyn Monroe. The history of the building itself is impressive and with it being good value to get in don't miss it out if you are in the Hollywood area. I discovered it late in the day and could have spent much longer exploring it than I had time for.
