Edward Penfield's “Harper's February” Valentine Postcard

A man in a mustard coat slips an envelope marked “TO MY VALENTINE” into a bright red mailbox while a woman in a plaid shawl and green hat waits beside him — Edward Penfield's “Harper's February” magazine poster, reproduced as a postcard. Deep cobalt blue and warm ochre carry the whole Art Nouveau composition.

• Size: 10×15 cm

A witty pick for a Valentine's Day card or a poster-art collection, and a change of pace from the series' Christmas cards.
