Surrealist Maiolica Earthenware Plate with Poetic Inscription

I recently snatched this up from a seller online, and am fascinated with the similarities to Joan Miro / Picasso's work. There is no marker's mark or artist's signature- only a poetic incised message on the backside. The back of the plate is marked SIEMPRE Y TUS OJOS NO SON MIO, which translates into "AS LONG AS YOUR EYES ARE NOT MINE". I have spent hours researching Mid Century Surrealist vessels and the natural handwriting of the masters, but simply cannot make a connection without the signature. Maybe this is just the work of an amazingly talented unknown?

Any insight or recommendations on where else to research appreciated! Thanks in advance!
