Not only is it time, I’d say it’s long overdue. Based on everything that the U.S. Postal Service asks of a stamp proposal, I put together a prospectus and created the samples pictured here. Should the proposal progress, I have someone in mind to help design the actual stamp; these are more proof-of-concept than final product.
So many proposals are submitted each year that the approval process can take up to three years. But even if it’s selected you might not be notified as to when the stamp will appear.
Still worth a try, I think.
If you like the idea, maybe put a +1 or something in the comments section and pass along a link or two; perhaps a showing of support would help influence the committee.
