A live show from my childhood

When I was a child, circa 1972-73, my parents took me to a live show and among other things, I remember the name: “The Magic Lantern of Praga”. I recall seeing live action combined with filmed sequences (a man in roller skates running in the streets), black background puppets, and a lot of strange things. Did anybody remember it? Could you tell me something about? It’s one of my early memories from the spectacle business.

I live in Mexico, and the title may be not accurate: “The Magic Lantern of Praga” or “The Magic Lantern, from Praga”.

I remember seeing them at Expo 67 in Montréal under the name Lanterna Magika.
