December 1963 envelope
Letter transcription:
December 1963, p. 1
Dave Dear – Thank you for sending the album. Talked to your mother yesterday. She tells me you [are] just slightly busy. We are having real jingle bells weather which means I am housebound. I do hope all goes well with you and Bonnie on your journey.
Much love,
Grandma

Just curious: how do you know this is from December 1963? The post-mark is damaged.
Well, I don’t really. However I put the letters in my binder in the order that they were banded together. Since the letter is addressed to you at IU, it could only be 12-1960, 12-1961, 12-1962, or 12-1963. Which year would it have been likely?
