 Since 1969 , public displays of artwork in Tulsa have been funded by one percent of its annual city budget . Each year , a sculpture from a local artist is installed along the Arkansas River trail system , while other sculptures stand at local parks , such as an enlarged version of Cyrus Dallin 's Appeal to the Great Spirit sculpture at Woodward Park . At the entrance to Oral Roberts University stands a large statue of praying hands , which , at 60 feet ( 18 m ) high , is the largest bronze sculpture in the world . As a testament to the city 's oil heritage , the 76 @-@ foot ( 23 m ) Golden Driller guards the front entrance to the Tulsa County Fairgrounds .
