Imprinted stamp from envelope, card etc. that was cut in the form of a square or rectangle.
a section of postal stationery, cut from the entire, which contains the stamp-like indicium. Cut squares are considered less desirable than entires. While cut squares from stamped envelopes are considered collectible, cut squares from postal cards are not.
A neatly trimmed rectangular or square section from a stamped envelope that includes the imprinted postage stamp with ample margin. Collectors generally prefer to collect stationery as entire pieces rather than as cut squares. Some older stationery is available only in cut squares.
