This stamp is one of a block of four offering a glimpse of what mail delivery might look like in the future. Pictured in the set are a hypersonic airliner, a shuttle at a space station, surface rover, and a mail vehicle traveling on a cushion of air. Although these vehicles don’t actually exist, they are based on the industry’s estimation of what future mail delivery transportation could look like.
