A student asked me a question about legal rights of DIN, and that I wanted to know for sure:
1) Is it legal to grab a vector drawing of DIN from the 90's, change minor details and sell it on the market with another name?
2) Is it legal to grab a print of DIN from the 1931, digitise it, change minor details and sell it on the market with another name?
I know that the original version was designed in 1931, so the rights should be public domain, right?
Maybe a company let say... Monotype, owns the legal rights of the font's drawing and naming. Is it still public domain?
It's not entirely clear at least to me.
Any help will be welcome!
