Family?

Hanging out together in a glass case at St. Vincent de Paul Thrift Store in Madison, Wisconsin. (Something about the posture, the lower lip, the downward gaze, arms held in close to sides. . .)

Hmmm. . .

On the left: the Bluetooth logo; on the right: the logo created by Max Körner (1883-1963), for  Behinger and Co. in 1922.

Thanks to Stephen Heller for pointing this out. (If you're interested in design, you ought to sign up for his highly entertaining and informative newsletter here.)
