Unsigned Etching

No signatures, numbering and title. Google images does not recognize it. I guess it could be a student piece but even so I find it strange not to be signed.
Thanks

 

I believe that's a signature under the woman's feet

 

yup !

 

I like this ! Ziboux ,maybe?

 

Salvador Dali (signature is reversed as in a mirror image)

 

Interesting.
Found this here:

"For some editions, the publishers were allowed by contract with Dali to produce an extended edition. These extended editions were clearly differentiated from the first limited edition by a signature in the plate (sometimes in reverse and within the image). According to A. Field, Dali never signed unlimited editions. "



Found it:
"Autumn (1970)
This second edition engraving is listed in the Field catalog as #70-2 and is limited to 1000 prints (first ed.: 150 in colors and signed, second ed.: 1000 in sanguine and signed in plate, total: 1150)"
