smilarities and differences

Both pictures show a view of famous works of art. As the left picture represents a twisted clock, the right one displays same object. And actually we could find the object in left picture, which built later, is the copy of the object exhibited in the right.
In contrast, they have different meanings. While the painting shows a broken clock, implying that the time is broken, the sculpture is smoothly twisted while is being slowly melted, suggesting that the time has a expiration date. Besides, the support is also different, the sculpture is held by a tree branch whereas the clock painting is leaned on the edge of a cube. To conclude, the clock painting is framed in a surrealistic place, as the rest of Dali pictures, on the other hand, the sculpture is placed in a public place only by itself.
