Q: I’ve been contracted to help the Los Angeles Public Library catalog their menu collection. In a recent donation from Lord Publishing Company, we have two proofs from the “Walt Disney’s Studio Restaurant” in Burbank. One is for the restaurant, as a whole; the other for “Counter Service.” Since they are only covers with no menu or inner content information, there is no date attached. I was hoping you could help me pin down a date (or range) for our records.
