In 1909, L.B. wrote and mailed this terrific congratulatory postcard to Marie for having been elected to “P.B.K.”, which in the context of the message and the card itself we know to mean “Phi Beta Kappa”.  Were we to be diligent enough, we would be able to learn if our guess is right … but it’s a happy old card, with stamp and postmark, and deserves a new home.  Grade: 1
