Galerie Bischofberger, Zürich (label verso). In 1982, Warhol's long-time friend and gallerist Bruno Bischofberger asked him to create a series of small works for children. Warhol responded with 128 silkscreen ink on canvases with acrylic additions known as Toy Paintings. The art was inspired from Warhol's personal collection of childhood toys. These works first went on display at an exhibition entitled Paintings for Children at Bischofberger's Zurich gallery in 1983. The works were displayed against a Warhol designed wallpaper of silver fish swimming across a blue background. Each canvas hung at the eye-level of a three to five-year-old child causing adult viewers to crouch or squat to examine them. An entry fee was charged for adults not accompanied by a child under six with the money going to a children's charity. The playful exhibition reflected a childlike freedom of experimentation. Warhol's FIPS Mouse (Wustenspringmaus) is painted in a palette of bold red, turquoise blue and clean white hues as though it should be viewed using 3-D glasses. Other paintings from the series included a drumming panda, an airplane, a parrot, a spaceship, a police car, and a helicopter. The imagery was appropriated from the box covers of vintage and wind-up toys. By focusing on the packaging and not the object, these works reference commercialism and Warhol's earlier work including Campbell's Soup Cans and Brillo Boxes.
