Leah Rachel von Essen writes: “The first thing to know: the process of choosing and designing a stamp starts with you. As long as the subject matter fits the criteria outlined on the USPS website, the public’s ideas are brought to the Citizens Stamp Advisory Committee. The criteria includes a few aspects people might not realize before submitting. For example, beginning in 2018, proposals for a deceased individual will be considered three years following their death, and living people are not currently considered.”
