This two‐story brick building was constructed by Dr. J.N. Thomas to house Mansfield’s second post office on the ground floor and Dr. Thomas’ office on the second floor. 

Dr. Thomas and his son, Dr. Raymond Thomas moved their office to the back of the Chorn Drugstore in 1929, and the second story hall was purchased by the Woodmen of the World Life Insurance Society, Walnut Creek Lodge No. 273, which was chartered in Mansfield on April 8, 1897. 

In 1956 the post office moved to a new building on the west side of the street. Although in poor condition and altered, the structure anchors the northern edge of the potential Main Street Historical District and possesses historical significance for its use as a post office.

This building is a registered Mansfield Historic Landmark.
