Lee reynolds painting

Hi there everybody.

I was wondering weather anybody could help me understand a little bit about this picture.

It has been given to myself and my partner by a family member, as a move in home means they no longer have room for it.

I am aware that the artist is LEE REYNOLDS from the signature at the bottom. What I don't know is weather it is a common or unseen item.
also what is the value of this type of piece.

Off of the top of my head I believe the dimenssions were either 6x5ft or 5x4ft.

Thank you in advance for any helpfully feedback and advice.
