​The Antique Doorknob Collectors of America will hold our 45th Annual Convention

 Oklahoma City at the Embassy Suites Oklahoma City Will Rodgers Airport Hotel.

This should be an exciting opportunity for collectors and historic preservation 

enthusiasts​ to gather again as we have since 1981 to buy, sell and trade hardware,


​and share ideas & thoughts.


​The  2025 ADCA Convention  will be 

Open to the public Friday, September 12, 2025


​Oklahoma established as an Indian territory for tribes forcibly moved from the south.  Pressure for land lead Congress to change the ownership of the land from the tribes to individuals and make "extra" available.  This led to the great land rush of 1889. Oklahoma became a state in 1907 and Oklahoma City the State Capital in 1910.

The adjacent slides from the Oklahoma Arts Council show the beauty of the Capital building.
