Is the VM an autograph or copy?

[Scarecrow]

I suspect it's a group project, as well.

My top pics are family project, or possibly a group of university students, or possibly some apprentices at a studio.

A family project I could agree, but what level of family we should have to be able to produce VMS? Not a plain common family I would think.
University students maybe had access to the required techniques and knowledge, but skills and resources.. no idea. The complexity of the VMS especially in some parts, doesn't look like student's best pass time to me. Same goes for apprentices. I see some more coherent complexity in the VMS, that students and apprentices did not have potential to do. Just an opinion.

Thanks!
