The Willett-Thompson Collection, comprised predominately of older material from the 19th and early 20th centuries, is a closed collection at the PMCC Museum, physically mounted in more than 400 protective albums. The collection was largely assembled more than sixty years ago. There are pieces in this collection from post offices from which no full covers are known. The entire collection has been scanned by PMCC volunteers.

The files are largely in .JPG or text formats. Here are samples of individual pages from the collection: Ord, Nebraska [NE 578]; North Platte, Nebraska [NE 530].

Each CD includes a gallery of selected Post Office photos.

The Willett-Thompson Collection has previously been available and sold on a set of CDs or DVDs. For current ordering information, e-mail: directory@postmarks.org with subject line WTCD.
