Just created this upscaled version of a Jefferson Airplane poster seen in The Holdovers for a poster. Figured I’d share in case someone else has use for it.

This is the original: https://i.pinimg.com/originals/52/2f/45/522f451a9cf5d7fa1238907b4ac5264a.png

Upsized via AI, then reduced to 3 colors. Some edges are a bit jagged and aliased, but not too badly.

EDIT: New version based on a higher quality origin image, fixes the jaggy edges for the most part and better colors
