Support Kostman's original painting of Rosati was not a very accurate portrait. ██████████ ████ ████████████ ██ █████████ ████████ ██ ██████ ████ ███ ██ █ ████ ████████ ████████████ ██ ███ █████████
The argument starts by mentioning how Kostman's painting of Rosati was an inaccurate portrait. It then uses that fact as a premise to conclude that a copy of Kostman's painting will necessarily be an inaccurate reproduction of that painting.
Let's track the flow of the argument here: Because Kostman's painting was a bad representation of Rosati, the copy of Kostman's painting will be a bad copy of that painting. More abstractly, because B is a bad copy of A (what Rosati really looks like), C will be a bad copy of B. The flaw in the reasoning here is that the inaccuracy of the first work (B, Kostman's painting) doesn't somehow "carry over" to guarantee that the second work (C, the next artist's copy) will be a bad representation of B.
As an analogy, just because you take a blurry picture of a tree doesn't mean you can't make an accurate photocopy of that picture. You can! The photocopy of the blurry picture can be 100% accurate. It'll just also depict the tree blurry. This kind of argument would be a little more plausible if it said C would be a bad copy of A: the copy of Kostman's painting will likely still be an inaccurate representation of Rosati, and the photocopy of the picture will still show a blurry image of the tree. But as the argument stands, it assumes that the inaccuracy in one given object or process (Kostman's painting, which inaccurately represents Rosati) has to carry over to the replication of that object or process (the copy of Kostman's painting). That's the flaw we're looking for.
