A 1970s Sony Walkman TPS-L2 stereo personal cassette player made from blue metal with plastic internal parts and case. This model was the first Sony Walkman and has the world's first lightweight headphones enabling the owner to listen to music wherever they were. The concept was also branded as the Stowaway, the Soundabout, and the Freestyle before the name 'Walkman' stuck. This example is complete with its original instruction manual and associated ephemera from original purchase. It has an acrylic window and an RF welded PVC (leatherette) case and headphones.
