The ‘classic’ Photo Booth series:
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).
