Business papers, correspondence, proposals, contracts, specifications and records of the architectural projects of the firm Thomas Williamson and Associates, later Williamson-Loebsack and Associates. Each box contains records of several architectural projects, typically holding a different set of records. For example, specifications for multiple projects are in a box together, color schedules for multiple projects together, contractor materials for multiple projects together, etc. The pdf attachment is a specific listing of project material in each box, however it is not necessarily in the order listed on the document.
