On March 26, 2015, in New York, NY, the U.S. Postal Service issued the Martin Ramirez First-Class Mail stamps in five designs, in a pressure-sensitive adhesive (PSA) pane of 20 stamps (Item 472700). Five new commemorative stamps honor Martìn Ramìrez (1895–1963), who, while virtually unknown in his lifetime, is recognized today as one of the great artists of the 20th cen­tury. Each stamp features details from one of five of Ramìrez's more than 450 drawings and collages. Although confined to psychiatric hospitals for more than 30 years, Ramìrez transcended his own situation to create a remark­ably visualized world free from the constraints of borders or time itself. The back of the stamp pane includes verso text. Art director Antonio Alcalá designed the stamp pane.
