I thought I’d share this, it’s taken from a patent from 1937. Was this a typical thing in patent illustrations/engineering diagrams around that time, or was this just a bored technical illustrator doing some experimental typography?
i’ve spent a lot of time at Google Patents in the past, and I’ve seen this particular style ... a quick search finds two kinda similar ... but there are a bunch of varied styles — different draftsmen trained differently.
it’d be great if someone did some more research in this area.
