English to Czech Art/Literary Art, Arts & Crafts, Painting information brochure on contemporary art appreciation

I need Czech terminology understandable to two target groups. 1) with reading skills of 10-12 year-old readers, 2) 16+ year old readers, for translation of a brochure on contemporary art appreciation.

Quote from the text: "Contemporary art is art that has been created since the 1970s. It is known for using a variety of materials, subject matter and forms. Wall art, sculpture, photography, fibre art, performance art and street art just a few examples. You will find contemporary art in museums and galleries and also in public places such as the sides of buildings."

Našel jsem "nástěnné umění", ale moc se mi to nezdá...
