At first glance the modest living room with parquet floor and track lighting resembles any space with an indifferent housekeeper: papers abound, stacks of paintings lean against walls, an indistinct jumble of items swallows a small table. But then Russell L. Goings starts pulling out what he calls his “stuff,” and his home improbably transforms into a personal art gallery, one brimming with his extensive collection of work by Romare Bearden, the 20th-century artist best known for his soulful collages of African-American life. Bearden also happened to be Mr. Goings’s longtime close friend.
