Tyrannosaurus T. Rex Lenticular Flicker US Dinosaur Prehistoric Animal Stamps !

Description

This is a set of four genuine commemorative United States postage stamps featuring Tyrannosaurus Rex. The stamps are in mint, never hinged, post office fresh condition. The stamps are
unusual
in that they have a special
lenticular
coating that causes a flicker effect so that the image on two
of
the stamps changes when the stamps are tilted. The stamp at the upper right changes from a T. Rex looking
to
the left to one that
shows him with his
mouth
wide open. The stamp at the lower left changes from a
skeletal
display of T. Rex to one with a full skin covering. Shipping discount offered for multiple lots paid for at the same time in one payment, so please view my other listings. Thanks for looking!
