This is a 60s Blocks open-collar printed flannel shirt. It's an old shirt made in the USA by a well-known brand, and open-collar shirts from this brand are often traded at high prices. With its cool color scheme, this shirt is easy to wear and can be used as an accent color for your inner layers. Regarding the condition, there is some fuzziness typical of flannel shirts, but I believe there are no holes or other damage such as stains. Size...M
