After being hinted at by Union owner Chris Gibbs, the Los Angeles streetwear pioneers are continuing to tease an Air Jordan 4 project.

The latest teaser includes an image of designer Tinker Hatfield's original Air Jordan 4 sketch from 1988, which is possibly indicative of the direction Union will head with its collaboration. Key differences between this sketch and the retail version of the Air Jordan 4 include a zebra-embossed durabuck overlay and the extension of breathable mesh across the full length of the tongue.
