department store offering clothing, furniture, rugs, housewares and a toyland in the basement at Christmas. It was the city's largest department store during its existence, and claimed to be Iowa's largest department store at the time of this building's construction. In 1970 another Davenport department store, Peteresen Harned Von Maur, bought Parker's. They operated a budget outlet for their store here until 1974 after they closed Parker's. The upper floors of the building were converted into office space after that. Among the tenants in the office space were the accounting firm of McGladrey & Pullen, later RSM McGladrey, and Verizon operated a call center. The main floor retail space remained empty. Putnam Center Building Between the Putnam and Parker buildings is a two-story infill section. It was originally designed to complement the two towers. However, that structure was never built as funds were not available for its construction until the mid-20th century. Until then, the building that originally stood between the Putnum and Parker buildings was a four-story gabled structure built by LeClaire in the 1850s. The second floor was converted into a "shops building" that contained 16 to 20 shops lining an interior corridor. The old building suffered damage because of a fire on September 3, 1926. As a result, most of the upper stories on the back of the building were removed and the shops building concept was discontinued. Plans for the current structure were drawn up in 1955 and construction was completed in 1957. The original folded yellow brick facade was remodeled in the 1990s. Rather than having a unified appearance as originally envisioned, the Putnam-Parker Block appears to be the three separate structures that it has always been. Most of the Putnam Center Building housed the downtown J.C. Penney store until it moved to the newly constructed NorthPark Mall on the city's north side in 1973. The building continues to house retail establishments in its four storefronts. More windows were added to its second story when the building was renovated in 2017. Unlike the Putnam and Parker Buildings, the Putnam Center Building is not a contributing property in the historic designation.
