A fishing boat with frozen rigging is docked in Portland harbor in this Press Herald photograph from January 1955.

This photo comes courtesy of the Portland Room of the Portland Public Library, which is in the process of organizing and conserving the archival collection of original Portland Press Herald, Maine Sunday Telegram and Evening Express photographic negatives — a major collection that spans from 1937 to the 2005. In Flashback, we’ll share some of the highlights, as the archives continue to take shape. Find more at www.pressherald.com/flashback.
