The product is a collection of 37 BLOCKS of three-cent postage stamps from the United States, most of which were issued in 1958.

These stamps are described as being Mint Never Hinged, meaning they are in pristine condition and have never been used. 

The stamps feature a variety of colors and are ungraded and uncertified.

These blocks of stamps would be a valuable addition to any collector's United States postage stamp collection.
