This week's prompt asks that you consider postage stamps.
Write a poem that focuses on stamps in some way, or at least mentions a stamp/stamps.
Your poem's speaker could be licking a stamp, decorating a tray with stamps, dating a philatelist, or mulling over the history of stamps, or any other number of things. Let your imagination stamp itself into your writing!
Information about stamps can be found in many places, both IRL and online, but you can start here: Smithsonian National Postal Museum.
