Antique Handmade Valentine: To My Love, Less Swap Hearts

Yesterday I came across a bunch of old handmade valentines, including this one, filling me with total joy. This one perhaps gives the most joy of all, with the misspelling of "Let's" inside, reading instead "Less Swap Hearts" instead.  Love.

4 7/16" x 4 3/4" closed and in very good condition.
