The company town of Itmann was built in 1916. By 1917, the company was mining the Pocahontas No. 3 seam along the Guyandotte River in Wyoming County. This company store was build in the early 1920s and was the center of the coal community. Due to the Virginian Railroad, Itmann miners shipped two million tons of high-quality “smokeless” coal during the 1950s and employing 1,800 workers from West Virginia. The store was named for West Virginia financier Isaac T. Mann, the president of the Bank of Bramwell. He was an officer and principal shareholder in Pocahontas Fuel.
The store sat at the center of the town. The store was designed by architect Alexander Mahood from Bluefield, West Virginia and built between 1923 and 1925 by Italian immigrant stonemasons. In addition to the store, the building housed a post office, doctor’s office, freight station, payroll office, and other management functions. In the 1980s, both the mine and company store closed. The building was listed on the National Register of Historical Places in 1990 and is now privately owned.
