Launching June 2023, the postcard program adds an ephemeral facet to the Biennale, inviting artists, writers, collaborators, Biennale team members, and SeMA staff to contribute their own personal, philosophical, abstract, or affective maps through images, photography, or text. These submissions are printed and circulated around Seoul and may be collected as keepsakes or sent to friends by post, creating an unusual communal map through acts of contribution, compilation, and distribution.
