Sickle Cell Awareness 37-Cent Postage Stamps (Vertical Pair with Selvage)

This item consists of a vertical pair of United States 37-cent postage stamps issued to promote sickle cell awareness. The design features a heartwarming illustration of a mother kissing her infant child, stylized with a soft, warm color palette including yellows, browns, and whites. The text 'TEST EARLY FOR SICKLE CELL' is prominently displayed at the top in red lettering, with 'USA 37' and the copyright year '2004' (Scott #3879) visible at the bottom. These are self-adhesive stamps, evidenced by the characteristic scalloped, die-cut perforations. The pair includes the top selvage (margin paper), which is blank and white. In terms of condition, the stamps appear unused and in good color preservation, though there is visible debris or possible foxing/staining along the right perforation edge and bottom corner of the lower stamp. The serrated edges show some slight irregularities consistent with being separated from a larger sheet. The printing quality is high, utilizing multi-color photogravure or offset lithography common for early 2000s USPS commemorative issues. The overall style is representative of modern humanitarian commemorative philately, focusing on public health awareness.
