The 'Classic' Photo Booth Series
According to Yahooda's website, "The Photo Booth series started in 1974. Every month systematically, between April 1974 and April 1990, one set of pictures was taken in the ‘classic’ Photo Booth. (format: a vertical strip of four pictures). Subsequently the time lapse changed to every three months. The series changed in 2006 when the ‘classic’ Booth was replaced by its digital equivalent (format: square)."
