Analysis Summary:

The article is mostly accurate, with the main claim about the calligraphy breaking auction records supported by multiple sources. The framing of Ahn Jung-geun as both an "assassin" and an "independence hero" introduces a degree of bias, though it reflects the complex historical context. Some details, such as the specific price the calligraphy fetched, are not consistently covered across all sources.

Detailed Analysis:
