Package allusion

It seems we know famous works of art. We often refer to the paintings of great artists and discuss them. Are our memories correct? Is it absolutely necessary to know the classics in details? Or are blurry, fuzzy memories quite enough? Do we need to correlate our impressions of the masterpiece with the original? Maybe light allusions are enough to evoke vivid memories. How did we feel when we saw these paintings for the first time? After all, any masterpiece can be made from plain improvised material. For example - garbage bags. By means, of these (so-called) "copies", we feel the joy of recognition. And we can exclaim: "Oh, I've seen it somewhere!"
