The McCleery Calendar Factory, also known as The McCleery Company and McCleery-Cumming Company, is a historic building located in Washington, Iowa, United States. Hugh H. McCleery started the business in the basement of his home on East Main Street in 1905. He expanded into a small building behind his house in 1910 and then into a two-story building at the rear of his lot in 1913. This two-story brick structure was built two blocks to the north in 1923. The original section of the building was L-shaped and the "L" was filled in by an addition constructed in 1931. Another addition on the back of the building was completed in 1935. In 1944, McCleery acquired the calendar division of the Newman-Rudolph Lithographing Company of Chicago, and the company name was changed to the McCleery-Cumming Company. A single-story office addition was completed on the west side of the building the following year. The company produced calendars for distributors across the United States, who then sold them through their network of salesmen. Because of this, the McCleery-Cumming name was never on the calendars. By the late 1950s, they were the second-largest manufacturer of religious calendars in the country, and they became the largest employer in town. The company moved into a larger facility on the south side of town in 1958. They were locally owned through 1993 when the company was sold to Bemrose USA. They continued to operate the factory in Washington until 2004. This building was listed on the National Register of Historic Places in 2015.

Phillips Coal and Grain and Freshwaters Coal and Supply, is a nationally recognized historic district located in Washington, Iowa, United States. It was listed on the National Register of Historic Places in 2015. At the time of its nomination it contained six resources, which included four contributing buildings, one contributing structure, and one non-contributing structure. By 1910 there were five businesses in Washington that sold coal to retail customers. All of them sold coal in conjunction with at least one other commodity. Henry A. Baxter was a dealer in coal, grain, and building materials. Baxter bought a grain elevator, no longer extant, on this site in 1903. He then had new buildings constructed in the 1910s and 1920s. Baxter was the only coal dealer in town that operated a coal elevator. Baxter died in 1929, and his company continued to operate through the 1930s. It became the Palmer Coal Company and Bush Coal Company in the early 1940s. Howard F. Freshwaters bought the property in 1945. Freshwaters Coal and Supply operated here from 1945 to 1959. Coal usage declined through the 1950s as natural gas replaced it for heating buildings. In 1959, Freshwaters Feed and Grain Company moved to this location from downtown. They continued to offer coal for sale into the early 1970s, and they were the last business in Washington to do so. The contributing buildings include the brick office building (1912), the concrete block delivery stables (c. 1912), the concrete block/stucco garage (c. 1922), and the frame/metal feed warehouse (c. 1940). The concrete coal elevator (c. 1920) is the contributing structure. The non-contributing structure is a metal grain bin (1972).
