Discover the stories behind Colorado’s towns, trails, and communities—told through its postal history.

In the early 1980s, a small group of dedicated Colorado postal history collectors set out to create an organization devoted to preserving the state’s rich postal past. Although early efforts at ROMPEX were ultimately halted due to health challenges, the vision lived on.

That vision became reality in 1986 when Colorado collectors once again gathered at ROMPEX and formally launched the Colorado Postal History Society. At that pivotal moment, Bill Bauer stepped forward with an ambitious proposal—to publish a quarterly journal and ultimately develop a comprehensive Colorado Postal Encyclopedia as part of the Colorado Postal Historian.

With that commitment, the Society was reborn and has continued to thrive ever since. Today, the Colorado Postal Encyclopedia—an extraordinary 2,600-page resource—has been completed. In 2013, Steve Morehead, with the assistance of Roger Rydberg and Joe Ditlow, undertook the task of editing the Encyclopedia and transforming it into a fully digital publication.

The Society now publishes the Colorado Postal Historian on a quarterly basis, edited by Bill German. Each issue features Society news, meeting information, and—most importantly—an in-depth, multi-page article highlighting a Colorado post office and the history of the surrounding community. Prospective members are invited to request a complimentary see-sample copy by sending their name and address to the contact below.

Members and guests are always welcome to attend Society meetings, held at 1:00 PM at the Rocky Mountain Philatelic Library, 2038 S. Pontiac Way, Denver, Colorado. You are also invited to join us at our annual meeting during the Rocky Mountain Stamp Show on May 9, 2026. Learn more at rockymountainstampshow.com.
