Here's a a fun little item. This menu features Disneyland on the front and back covers. The date on the inside shows "Thursday May 22nd". There was a Thursday May 22nd in 1958 but that's too early, there's a monorail photo on the back cover! The next available Thursday May 22nd was skipped (1964) blame leap year. So this must be from Thursday May 22, 1969.
I'm not 100% positive this is a train menu, but the Streamliner Fruit Plate is a clue. Pickled Herring in Sour Cream, I just lost my appetite. OK, the Lemon Sherbet might get my appetite back.
If this is from 1969, that 1958 Cadillac is looking just a bit dated.
Here's both front and back covers scanned together.
