Key metric: Cultural Preservation Index

As a social scientist, I analyze that this article highlights the intersection of art, culture, and modernization in South Asia. The photographer's extensive documentation of regional bus art serves as a critical preservation effort for a declining cultural practice. This decline, attributed to government policies and mass production, reflects broader tensions between traditional expressions and modernization efforts. The project's importance lies in its potential to raise awareness about vanishing cultural artifacts and potentially influence policy discussions on cultural preservation in rapidly changing societies.
