Homemade recordings - NOT amateur radio

Some months ago I chanced upon a recording made in the 1960s. It is of my own voice recorded on the plastic lid of a coffee tin made with a school friend! This is pure analogue. My problem is I no longer have a means of playing it.

To this day, I find this fascinating, that just a large horn a piece of plastic or metal and a very loud shout is capable of recording my voice. 60 years later, my teenage voice is still imprinted.
