This is Robert Indiana's large original 1970s vintage Parrot, with Eureka - written in Cyrillic letters, from the 1971 Decade portfolio - NOT to be confused with a later version of the same print, smaller in sized and published in an edition of 395 - from the 1990s. (This one is the larger, more desirable, original 1970s work - was from the edition of only 200).

There is some age wear to the back (verso) which won't be visible when the work is framed.
A terrific Robert Indiana print from one of the most influential periods of the artist's career.
