Thoughts on this one? Surrealism? Educate me :)

So sometimes, I find researching easy, and other times no. The more we learn though, the better we become eh?
This piece is gouache (I believe) on masonite, 24" x 30". Would it be considered Surrealist? Does anyone recognize the sig. on the back? Obviously any input is really appreciated

 

I'm trying to find a signature on one of Marlie Muls pieces. Here is something she did. The rest I found is far more out there.

 

Not gouache, which is really a heavy watercolor. Looks like acrylic to me. This might qualify as surrealism.

 

Agree acrylic and I’d call it a surrealist abstraction.

 

With heavy impasto.
