WPA writer Sara B. Wrenn's oral history interview, in January 1939, with a persnickety collector/hoarder of historical artifacts named Miss Mertie Stevens, including some Oregon Trail objects dating back to 1842! As a side note, writer Sara Wrenn does not seem to have liked Miss Mertie very much. (For the transcript, see https://www.loc.gov/item/wpalh001977/ )
