Sept. 1, 2015, photo by Derek Davis/Staff photographer; 1948 Maine Sunday Telegram photograph courtesy of Portland Portland Library Special Collections & Archives (photographer uncredited)

The black-and-white photograph above appeared in the May 23, 1948, Maine Sunday Telegram in a full-page advertisement for the “Minit Man Car Wash” grand opening, located at the Century Tire garage on Marginal Way in Bayside.

The garage closed in 2014, and as can be seen in the Sept. 1, 2015, shot of the same scene, the site is now under demolition to make way for a strip mall.

The Portland Room of the Portland Public Library 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 2005.
