A question for Roger Dean fans and fantasy artwork fans

Back when I was in my teens and listening to Pink Floyd "Echoes" (the album Meddle), I had a poster on the wall. I always thought it was a Roger Dean poster. It was mainly beiges and browns with flying dragon type animals. If I remember correctly, they were flying over large waves or mountains.

I have been looking at Roger's website and have not found any artwork that is the same. SO, my question is does anyone know any other artists that are extremely similar to Roger Dean?

The poster was purchased somewhere around 1976-79. Readily available in Spencer’s at the time.

Thanks.
