BOSTON (CBS) — Do you recognize anything from these pictures? The State Library of Massachusetts has five old photos of construction projects but no information to go along with them.

“What we want to know is: where the photo was taken (city/town, neighborhood, street, etc.); the approximate date on which it was taken; and what construction projects are being depicted,” the library said.

Anyone with information is asked to email
