We found out about this Letter from a comment left on my collaboration video with Tolkien Talk tête-à-tête with TolkienGuide's Trotter on our YouTube channel.

I watched the video mentioned and at about 3 minutes in, a Tolkien letter is mentioned.

I asked if we could add the Letter to the Guide and have added it today as Letter number 2240

Letter from J.R.R. Tolkien to Miss Nicholson • 13 October 1955 (#2240)

Thank you for sharing the letter contents with us, and if anybody else has or knows about any letters either to or from Tolkien or about the Professor, then we would love to add them to the Guide.
