A set of 2 plaques commemorating the first date of their respective stamps were issue (one features the Statue of Liberty and the other oil lamps). They are each 8 1/2 inches wide and 6 inches long and in good condition. A wonderful addition to any stamp collection. Found them packed away, with so many other items and so many loose stamps/booklets.
(A $2.00 fee has been added to the price for insurance during shipping.)
