A Parker Branch Bookwork, OLM or “Old Leather Man” is the name given to a “tramp” who was documented in the late 19th century to have repeatedly walked a loop between Connecticut and New York state that was almost always completed in 34-day intervals.
As an illustration of the arbitrary relationship that exists between the official systems of time-keeping or measurement and natural activity, Parker Branch adapted the records of the OLM’s passage through Naugatuck Junction as a system to determine the contents of an anthology of dates and associated global historical events titled OLM.
