Look at all the windows!  This E.G Kropp (Milwaukee) post card carries a Kingsport postmark for July, 1937.
It was mailed to Eccles, WV. The message, in a somewhat cramped script:

Hello! Honey! Read your last letter yesterday. We came to Norton last Friday. Sue, M.F. and my-self came to Kingsport Tuesday.  Sue & M.F. have (something, something…I’m working on it – the script is hard to read).  Will go  home Monday.  Will write a letter then. Love, Mama
