An office block of about eleven stories on the northeast corner of Sixth and Olive. A dark, rusticated base rose through the lower floors in a row of tall round arches, each framing a projecting bay window above the shopfronts. The shaft above was pale brick, with its windows set in pairs, and the top story was hung with carved wreaths and swags of garland beneath a deep, overhanging cornice.
The Carleton Building stood on the northeast corner of Sixth and Olive, in the heart of the downtown office and shopping district. The 1909 Sanborn map shows it as an eleven-story office building of fireproof steel-frame construction at 300–310 N. Sixth and 521–523 Olive, with a basement restaurant and kitchen. In the 1920s its arched lower floors held shops and upstairs showrooms, among them Jamerson Clothes and the Busy Bee candy store. The building was demolished sometime after 1967, and a modern office tower now occupies the corner.
