Many Marylanders and horse enthusiasts are dusting off their fancy hats and cocktail kits in anticipation of the 148th running of the preaknessstakes, the second leg of the annual thoroughbred triple crown, at Baltimore’s Pimlico Race Course. Though the club houses have changed, horses and jockeys have raced at Pimlico, affectionately known as “Old Hill Top,” since 1880 in Baltimore’s Park Heights neighborhood. It is one of the most enduring venues in American sports. We need your help! This glass plate negative in our collection shows a race at Pimlico Race Course but lacks a date! Can any sleuths place this image in time? When a photograph lacks a precise date, clues such as the camera technology employed and the clothing and built environment depicted help historians add an approximate “circa date.” Pimlico Racetrack, Unidentified Photographer, No Date, MCHC H.
