From 1925 to 1958, the Pennsylvania Railroad Company issued a series of advertising calendars, each measuring over two feet square. Of the thirty-three calendars published, twenty-eight were illustrated by Grif Teller (1899-1993). This small collection consists of six posters featuring the paintings from the 1949, 1950, 1951, 1953, 1954, and 1955 Pennsylvania Railroad advertising calendars. The title of the painting and the words "Pennsylvania Railroad" appear in the border beneath each image.
