USPS Certified Hat
For some people, it is a means for delivering important documents to their clients, or to their lawyers. For others, it is a way to share family moments and class photos with the grandparents and other relatives. For some, it is a hat. The U.S. Postal Service document mailer makes a great head cover for those early morning naps in the Boston subway system. Get yours today at your local U.S. Post Office. Don’t be fooled by those plain manilla envelopes found elsewhere. Get an official, high-quality envelope from your nearest Postal Service representative.
Taken in the Park Street Station of the Boston Red Line subway system.
