Here's another variant. I can't see Beck's name on it, but the schematic
map is certainly in his style:

Yes, I came across that, apparent, plagiarism of Beck's efforts.

"This extraordinary world map by noted Bauhaus designer and artist, Laszlo
Moholy-Nagy, draws on the pioneering information design work of Harry Beck
and his London subway maps"

Hmm. "draws on" - spelt p-l-a-g .....

I think plagiarise implies copying something pretty much intact from one
work to another. This instance is simply very much "in the style of".
