Apparently, the sole common denominator of the objects in the collection — which range from paintings, photographs, and record sleeves, to a can of green paint, a German car license plate, and an ouija board — is to have appeared as illustrations in an issue of The Serving Library Annual or one of its immediate antecedents, Bulletins of The Serving Library or Dot Dot Dot, sometime over the last 20 years.
In fact, this issue of the Annual bears a family resemblance to a book published by Roma Publications in 2009, Extended Caption, which reproduced 43 items from the collection that had originally illustrated as many Dot Dot Dot articles, which were in turn systematically presented as captions to the items.
