Where can I find paintings by the spanish artist Manuel Munoz Ruiz?

Manuel Munoz Ruiz was born in Granada, Spain, in 1948. He did a lot of demonstrations in the 1970s, 1980s and appeared on tv in America. He used to have a gallery in the marina at Puerto b, in Marbella spain, that sold his paintings, and also the Ruiz Museum in Marbella itself. They have both closed down, and I can't find any information about why, or where the paintings moved on to. He's an oil painter, but in a 3D style. He uses blocks of colour, like slices of er, to make his paintings.
