Dial 9 for an outside line. flip flops

The artwork on these Flip Flops is an original graphic pattern of old fashioned telephones, the rotary dial styles used before push buttons and cell phones existed. Originally they were always black. But then things became exciting when phones came in colours like light blue, gold, green, white, and red for emergencies! The old phones plugged in with spiral cords that stretched, represented by the red zigzag lines in the pattern being stretched to the max. The background is a black texture with flecks of colour, like the faux marble patterns on the modern material of the 1950s, linoleum. The rotary dials had all the numbers and symbols, but the number 9 in the graphic is the number to dial for an outside line in large companies.
