In the mid nineties someone sent a card to me with a print on the front of a man and woman on horseback. The horse is white and may have wings. There is blindness in the picture but I can't remember if it is one of the people or the horse. The rider at the front's head is half turned and the woman's breasts are exposed.
I'm almost certain it was called The lovers and I thought it was by Chagall but I can't find it listed under his work. Does anyone recognise this painting and know who the artist is?

Eirene

Is this the one?
