Boston's Museum of Fine Arts is building a new wing.
A construction worker knocking down a wall spotted an envelope sticking out of the rubble.
Inside was typed note.
It was written by the man who helped oversee the original construction more than 80 years ago.
Thomas F. Crowley said it was 95 degrees on July 21, 1926 and had information on how much his workers were making.
The Boston Globe reports the pay ranged from 74 cents to a buck-50 an hour.
Museum archivist Maureen Melton says she's trying to learn more about the man who has given them a glimpse into the past.
