The upcoming celebration of Aunt Mary's 90th Birthday at Yosemite prompted this letter from Joe of which this is the second page. Only the handwritten part is transcribed below.
Dear Aunt Jean and Uncle Harold,
Looking forward to seeing you in Yosemite. Many thanks for your co-sponsorship of this birthday party event!! I still haven't cancelled the 2 rooms of the Morgans and the Ashcrafts but will do so soon if I don't hear a positive from them.
Bring a board game, if you wish.
