This is a neat, color postcard(relatively clean; w/ minor wear and tear in the form of creases here and there) of El Morro and the entrance to San Juan Harbor sent from San Juan(w/ a great strike of the machine cancel!), Puerto Rico, U.S. Territory, to Essex Junction, Vermont, U.S.A. on August 22, 1923! The sender and addressee were both members of what looks like a post card club. As for the green, 1-Cent, "Washington," U.S. definitive, it is in very fine condition! Noted imperfections aside, this is a nifty piece of Puerto Rican and U.S. postal history!
