The listing, 1999 BOSTON TROLLEY POSTCARD by Klein Post Card Printed in E.E.C. has ended.
Up for bid is an unusual die cut post card, published by Klein Post Cards.
I have not been able to find another like it to compare. It has a linen-like surface on front, but smooth on back. I would think the shape might get caught in USPS machinery!
This one was saved as a souvenir from a business trip to Boston, and was an estate sale purchase. I have not been able to absolutely establish an age, but if I am reading the barcode correctly, the card was manufactured in 1999.
And it was printed in the European Economic Community, according to printing on the card back. In 2009, the EEC ceased to exist.
Interesting card for your collection! Smoke-free item.
