Help wigh artist of 70's art

Found this at my local thrift store - I lived the 70's psychedelic look, but can't make out the signature
Can anyone help?
Thank you!

 

Juan Carlos something. Vindala perhaps? Probably not going to help but... Why don't you browse the gallery's Instagram pages?

Interesting metamorphic image.

 

I read Videla

 

Thanks Debora, , but I don t have Instagram

 

I thought so too, but too script scribble to read for sure!

 

Found his grandfather:

 

AI image search results - started with signature, then pic if art when asked- it's responses seem human!

 

Last few
PS - if order is mixed up, I apologize - looking at the small images on my phone isn't as easy as it used to be (I guess I'm no spring chicken anymore)!

Also, it may not be a big deal & I'm showing my age - but AI seems so smart & realistic it's scary!
I'm thinking of the Terminator & the AI taking over!

 

I read JC Vindela. It would be very unusual if artists who sold through/worked for the Viota Galería de Arte wouldn't use their own signature.

 

It's unusual for an artist to sign a piece with the full date. Perhaps it's a caricature. What's the medium?

The AI, using the royal "we", reads to me like the essay of a seventh grader who was just trying to fill the page with obvious & repetitive stuff: this is a label; this is a gallery label; this is a frame; galleries put labels on frames; this label says Viota; it is from the Viota gallery... It then goes off in what has been called hallucination, although I think confabulation would be a better word, seemingly detecting that the signature starts with V, ends with a vowel, so therefore is also Viota. Do we really know that there were Viota family artists from a Puerto Rican artistic family?

 

The Viota Gallery wasn't established until 1987 so perhaps the piece was only framed there. (Enmarcados = Frames) I don't think that's Puerto Rican. I'd look to Spain. Something about the hand... The only Spanish language surname I can find that starts with "V" and has a "d" is Vidales. And "J C" only ever abbreviates two things in Spanish: Jesuscristo (Jesus Cristo) and Juan Carlos. I suspect the latter in this case.

I used to have two Spanish friends called José Carlos, also a possibility. There could be other possible combinations as well.

 

Ink or pencil

 

On?

My two cents as to what it's on ...

Did think it was a type of paper. That looks right to my eye.
