The argument concludes that the high resale prices of several artworks sold off by a museum settle the issue of whether the artworks were of high or low quality. According to the argument, the prices prove that critics were correct that the artworks were first-rate pieces.

The argument uses the increased resale prices of the artworks as definitive evidence that the artworks were truly of high quality. However, this doesn’t account for the relevant circumstances of the resale compared to when the works were first sold. The first sale was “discreet,” while the resale followed the critics’ public outcry about how great the pieces were. This could easily have affected the prices.
