Mystery solved

Yesterday's impassioned enquiry yielded the desired result and I now know the identity of the gift givers.

Thank you, my dear friends, for the beautiful print of a lovely part of my favorite city . Thank you, too, for the tasty treats you delivered "this weekend," and thank you for the visits, and the cards from the kids.  (Nice job on the cursive!)

I'm lucky that you are part of my sum.
