I received this envelope in the mail yesterday. I was so excited about the plethora of stamps - both modern and vintage - that I hardly cared what was inside. The one, two, three, four, and five cent stamps are all current, self-adhesive stamps issued by the United States Postal Service.
The Rising of the Spirit of Independence Stamp was issued in 1973, one of a four part series. The Frederic Remington stamp was issued in 1961 to celebrate the centennial of his birth. The 1961 James Naismith stamp commemorates the 1861 birth of creator of basketball. The American Woman stamp was issued in 1960.
