United States 3 Cents Postage Stamp, Robert Louis Stevenson

This item is a vintage United States postage stamp, likely from the early to mid-20th century. The stamp is predominantly a purplish-pink or magenta color, square in shape, with perforated edges characteristic of postage stamps. The central design features a bust portrait of a man, identified as Robert Louis Stevenson, facing slightly to his left. He has a prominent beard and mustache and appears to be wearing a collared shirt or jacket. The portrait is framed within an ornate, circular, laurel-wreath-like border. Above the portrait, stretching across the top edge of the stamp, are the words 'UNITED STATES POSTAGE' in capital letters. In the lower-left corner, the denomination '3¢' is clearly visible, indicating a three-cent value. In the lower right, faintly visible, there appears to be a smaller, stylized figure or emblem. The stamp shows some signs of age and possible environmental exposure, evidenced by horizontal lines, which might be creases or album page indentations, crossing the portrait, and a slight unevenness in coloration. The perforations appear intact, though some wear might be present upon closer inspection. The overall condition suggests it is a used or mounted stamp, given the visible lines. The specific color and portrait identify it as the 1940 3-cent stamp honoring Robert Louis Stevenson, issued as part of the Famous Americans series.
