Another interesting find featuring a Showalter cousin: Philip S. Hench.  Hench won the 1950 Nobel Prize for Medicine for his work with cortisone.  This postal card, envelope, and enclosed mini medal comes from Portugal in April 1977.  It features an envelope with four stamps from Portugal and a mini size medal (front shown on front and back of medal shown on back).  It’s a thick envelope.  Cool item measures 4 1/2″ x 6 1/4″.  Only one I’ve ever seen.

Added 7/28/20–I opened it! Curiosity won out and I found that there is a card stock inside with a place for coin.  There is a black and white photo of Hench inside on the card stock and some description in thee languages.  Again, this was limited to 172 pieces.  Mine is #37.  I still have not found any others like mine.  Maybe they all stayed in Portugal–with only a few slipping past the border.
