[Peter Blomberg]

Jumbo bricks are from 1964, so came after the patent. In fact, they had tubes themselves. Oddl you need to differentiate between Samsonite (US) and European ones here, since they have different aspect ratios - EU is 3x regular brick, Samsonite is 5x a Modulex (yes, for whatever reason ) brick.

Or do you mean something else?

My mistake. I didn't think that they would mix eras in the timeline, but apparently they did.
