On the front of the postcard is a scenic illustration of the Charles River Esplanade in Boston, Massachusetts. The image showcases a lush green park in the foreground with scattered trees and winding paths leading toward a body of water on the right. In the mid-ground, a variety of colorful urban buildings and architectural structures form the city skyline, including a prominent church spire on the left and a distinctive domed shell structure. The sky above is a pale blue with soft, wispy clouds. Text printed in the upper right corner reads CHARLES RIVER ESPLANADE, BOSTON, MASS. and a small identification code 5A-H1839 is visible in the bottom right corner. The postcard features a linen-style texture with a white border.

This beautiful esplanade runs along the Charles River to Charles Street and connects traffic to all northern points and Boston through under-pass of West Boston Bridge." Along the left edge, vertically, it reads "UNITED ART CO., BOSTON, MASS." In the center, running vertically, it says "GENUINE CURTEICH-CHICAGO "C.T. ART-COLORTONE" POST CARD (REG. U.S. PAT. OFF.)."
