This two-story, brick building sits on the southwest corner of Main and 7th, facing east, just south of the bridge approach. With the exception of the altered storefronts, it is quite intact and relatively well-preserved. The storefront display windows, transoms and entrances have been altered from the original appearance, but still retain the division of storefronts throughout and the transoms over the northernmost bay. The second floor windows, with decorative alternating brick trim, are topped with flat stone lintels with decorative keystones. The cornice, which extends below the parapet wall, has block modillions below it, a terra cotta or stone egg-and-dart course below the modillions, and a diaperwork pattern in buff-colored brick below that. The entrance to the upper floor is surrounded with black marble with the word "Andresen" above the door. A terra cotta cornice below the upper windows is intact, as is the architrave molding above the transoms.

Statement of Significance: This building was constructed in c.1902 by Solomon Garde at a cost of $20,000. It was sold to Burmeister and Andresen, one of the oldest mercantile firms in the city, in 1905 (Burmeister was listed as a jeweler in newspaper ads as early as 1887.) William Andresen, who had purchased a half-interest in C.L. Burmeister's watchmaking and repair business in the early 1890s, bought out Burmeister in the early 1900s, although he continued to operate the business under the name of Burmeister and Andresen for several years. An identical building (the Beaver Building) was constructed next door (south) by Andresen in 1910 (it was demolished in the late 1960s). In addition to the Burmeister and Andresen jewelry business (which occupied the north bay at 623 Main), the building houses two addition retail shops and provided several offices for professionals (commonly lawyers and doctors) on the second floor. Photos from c.1908 show a drug store located in the center bay, which is still listed at that spot on the 1911 Sanborn maps. The 1916 city directory lists the Raasch & Lamb Cigar and Tobacco shop at 619 Main, but does not indicate what business was located in the center bay at 621. Perhaps Burmeister and Andresen had expanded into the center bay by this time. The 1925 Sanborn maps indicates that Burmeister and Andresen occupied both the center and north bays and a clothing shop was listed in the south storefront. In 1941, Audre's (women's clothing store) occupied 619 and Burmeister and Andresen were still located at 623, but no business was listed at 621 {Burmeister and Andresen probably continued to occupy both spots}. By 1947, however, Mr. Pix Studio and Camera Shop occupied the center bay; Audre's was still located in the south bay and Burmeister and Andresen only in the north bay. This same arrangement was listed in the 1953 directories. In addition to his commercial interests, Andresen was one of the city's first commissioners and served three years as mayor. Although the storefronts have been somewhat altered, the building retains a high degree of historic integrity and conveys its historic appearance. It should therefore, be considered eligible as a contributing resource in the downtown historic district.
