Following his friend Berni Wrightson, Jim Starlin also did a Star-Lord piece:
This painting appeared on the cover of Marvel Preview #14, 1978. Starlin painted in this medium (oil? acrylic?) for many covers, portfolios, and series such as Metamorphosis Odyssey. It’s interesting that Starlin depicted Peter Quill without the helmet and wielding a sword instead of his blaster.
Ya gotta love that crazy cosmic afro chick in the foreground! Nuff said.
