This is a souvenir sheet (block of four) from the United Nations Vienna office featuring psychedelic artwork by artist Peter Max, created for the 1992 Earth Summit (Umweltgipfel). The artwork is divided into two horizontal pairs: the upper stamps depict a starry night sky with a Saturn-like planet, whimsical floating figures, and a radiating sunrise, while the lower stamps show a colorful landscape with mountains, a fisherman, wildflowers, and a sailboat on water. The sheet is printed in vivid, pop-art colors typical of Peter Max's signature style, and his signature is visible in the lower right of the artwork. The perforations between stamps are clearly visible, and the sheet appears to be in mint/unpostmarked condition.
Mistral
This First Day Cover features a vibrant souvenir sheet of four stamps designed by Peter Max for the United Nations Earth Summit (Umweltgipfel) in Vienna, June 1992. The psychedelic stamp artwork includes celestial imagery with a starry night sky, a Saturn-like planet, and a naturalistic landscape with mountains, wildflowers, a fisherman, and a sailboat. The stamps are printed in bright, pop-art colors and bear Peter Max's signature. The postmark is not visible in this image, and there is no cachet artwork on the envelope. The condition appears to be very fine, with clear perforations and no visible damage.
(The automatic summaries sometimes misidentify the postmark as part of the cachet artwork.)
