Overview

This is an original printed business or trade card for the Morgan Detective Agency, formerly situated at 120 Boylston Street in Boston. Featuring historic named telephone exchanges like 'Beach' and 'Mystic,' the card emphasizes '30 years detective experience and an unblemished reputation.'

Story

Long before digital surveillance, private eyes handed out cards like this across smoke-filled Boston offices. The named exchanges 'Beach' and 'Mystic' evoke an era straight out of classic hard-boiled detective noir.

Maker / Origin

The Morgan Detective Agency operated in downtown Boston during the late 19th and early 20th centuries, providing private investigative services ranging from industrial espionage monitoring to civil surveillance.

Condition & Value

Cleanly preserved with minor edge toning consistent with age, slightly uneven hand-cut left margin, and no prominent tears or heavy creasing. Ephemera in this clean, readable condition retains good collector appeal.

Value Drivers

  • ▲ Strong maker attribution with credible period details
  • ▲ Better-than-average condition for the category
  • ▲ Broader demand rises when presentation and finish feel intact

Concerns

  • ▼ Decorative-only demand limits the ceiling
  • ▼ Surface wear or missing provenance can compress the range fast
  • ▼ Regional sale lanes often underperform specialist venues
