Photograph of the entrance to the Sinclair building in Fort Worth, located at 512 Main Street. The building is in the Art Deco style. The entrance has a geometric archway in the shape of a step-pyramid. The arch is symmetrical with five distinct sections of decoration. The outer two sections are the smallest and feature a metal flower with geometric leaves on its stem. The inner two have what appears to be reminiscent of a fountain, also made out of metal. The center section of the archway has a variety of geometric patterns and shapes made out of thin metal. The band at the bottom of the arch, separating it from the building's identifier, is filled with triangular shapes. The building's name is written on polished marble, and it reads "SINCLAIR BUILDING." There are two sets of double doors below this, each with large metal kickplates. Shrubs sit in pots on either side of the entrance. There are multiple plaques on the walls by the arch, along with a sconce light.
