the potential of found objects

typically when creating a sculpture out of found objects an artist will pick something that is around the same shape. like in the picture of the dog sculpture the god head is made out of a lamp but it looks like the snout of a dog. the sculpture of the heart that is made out of the jug like container is shaped more or less like a heart would be in real life. also color could be a reason an object was chosen, like in the cow sculpture although cows are not yellow, red and white, there typically is white where the white is placed on the cow in this sculpture. also in the bird sculpture the pieces look like feathers but they are also a color that a bird could be in real life.
