Title: "No act of Love, however small, is ever wasted. Aesop." note card
Description: 1971? "No act of Love, however small, is ever wasted. Aesop." K(athy) Davis: Sweet Nothings. Recycled Paper Greetings. Gift of Mary Pat Ryan, July, '86.

Here are two pages of a card sent to Mary Pat by a friend. Mary Pat framed it for me. I am unsure of how the two pages fit with each other: most probably the "Aesop" and "Thank you" sides were #1 and #3 of the four-sided card. The saying raises a question for me: from where in "Aesop" did this saying come? I presume LM. Even more I am asking "In which version of Aesop in English" did this saying appear? It would make a fascinating but wide-ranging project to track all the sings which people attribute to "Aesop"! I have found Kathy Davis on the web and her signature, but I have not found this dear ephemeral card!
Date: 1971?
