The Boston Avenue United Methodist Church in Tulsa, Oklahoma is a masterpiece of art deco. It's also the subject of an ongoing squabble between two factions. One claims that the church was the brainchild of art teacher Adah Robinson, the other that it could only be the work of her one-time student and later prominent architect, Bruce Goff. I didn't come up with the definitive answer in my story for PreservationNation, but I have my suspicions.
