Hello Mario,

Thank you for your appraisal inquiry with Mearto. The item presented appears to be a photo-offset lithograph for the exhibition titled "Jasper John's Paintings and Drawings." The show was held at Leo Castelli's gallery in New York City on February 16 - March March 9, 1991. The poster was printed for promotion and features Jones's 1990 encaustic painting on canvas titled "Green Angel." Additionally, it was published in an edition of 1000 copies. The original painting is held in the collection of Walker Art Center in Minneapolis.

The estimate provided is based on recent auction estimates and results of this poster and other comparable unsigned exhibition posters for Jasper John shows. The estimate is contingent on a full condition report. Please note asking or dealer prices may vary. Thank you and please take care.
