Robert E. Jackson has been collecting twentieth century American snapshots for decades, amassing more than 12,000 pictures. From photographic gems like unintentional visual decapitations to outer-space themed Christmas cards, Jackson's collection highlights the unique anonymity of his subjects. For years, Jackson was interested in only snapshots from the late 19th century to the middle of the 1970’s, but recently he has begun to collect 4 x 6 borderless snapshots. This format was popular from the late 1980’s to around 2007 and signaled the last generation of analog vernacular photography.
