For over 30 years, the O's were our default baseball team. So we thought it was fitting to share this amazing photograph of the 1921 Baltimore Orioles. At the time, they were Class AA in the International League. Plus, this is a really amazing photo.

Take a look back at the 1908 Washington Senators, who finished the season with a 67-85 record, 22.5 games behind the Detroit Tigers for the pennant.

Take a journey back in time to explore the undeveloped Mount Pleasant of 1907 through a fascinating map. You can also see across 16th St. into what is now better known as Columbia Heights.

Take a trip back in time to 1929 and check out the Pennsylvania Railroad's "The Senator" in this awesome photo. Thanks to Shorpy for the amazing image!
