In the mid 1980's, I purchased a signed piece at an art auction and was told it was by Joan Miro "the younger." Miro usually signed his pieces just "Miro", my piece is signed "Joan Miro." I was told my piece is called American Football (Futbol) and I am unable to locate any information on this piece. Can anyone help me? In my research I know that Miro had a daughter and he has a grandson. In all of my research there is no mention of another younger Miro as an artist. My piece looks original and is very large. I would appreciate all responses. Thanks.
