The POSH, Inc. records consist of sketches, drawings, photographic prints, newspaper clippings, tear sheets and ephemera that document the work of company founder and designer Jay Anderson.

The items are organized by subject: notebooks and binders contain original sketches for the collections, along with fabric swatches and notes pertaining to prices.  Photographic prints and oversized black and white drawings show models in the finished pieces. The newspaper clippings document fashion shows, advertisement pieces, and local and national news items on Anderson and the company.
