An old sketch from last year’s homegrown that we could rework for the tour poster. It could be cool to put some instrument cases on top of the car to go along with the tour theme.
An eagle + guitar combo framed by some cool type and an ornate frame.
A vintage tour bus with a swirling collage of colors emerging from the back - the band name could be blended in with all the different shapes to give everything a cool cohesive vibe. I think this one could look really great when illustrated properly.
