- A colorful African Daisy graces a new Global stamp from the U.S. Post Service. This round Global stamp can be used to mail a one-ounce letter to any country to which First-Class Mail International service is available. As with all Global stamps, this stamp will have a postage value equivalent to the price of the single-piece First-Class Mail International first-ounce machinabble letter in effect at the time of use.
