THINGS IN MY LIVING ROOM LOCKERS

I have a set of 15 lockers I bought from the employee lounge of a store that was going out of business. Some of its contents include:
  1. A yellow rotary dial telephone
  2. Bert, Ernie and Pee Wee
  3. Viewmasters and Google Cardboard
  4. Polaroid camera and stereoscopic projector
  5. Random reading
  6. Mystery
    It came with a padlock I've never opened. Who knows what's in there?
