This is the very first letter my father-in-law wrote to his wife (both deceased). The letter is not dated but the envelope is postmarked May 14, 1962. They had been married four years when he was sent to Pasadena, California on a business trip, the first time the two of them were not in the same city once they knew each other. Thus, the need for the first letter.
Their home at the time in Vienna, Virginia still exists today, though it is much larger now. The very same motel (called then and now the Saga Motor Hotel) still exists at the same address. Only the phone number has changed, as the numbering system was later expanded to allow for more telephones throughout the country. The motel still advertises on its website that it is on the route of the annual Rose Parade, which is nationally broadcast on television every year in America. Notice that indication at the bottom of the letter.
Notice also that the motel's address printed on the letter has no mailing zip code and no two-letter abbreviation of the state, which would have been CA (for California). Those two conventions were put into use by the postal service the following year on a non-mandatory basis.
