Pharrell Williams and Jay Z's relationship goes back many years to when the two crossed paths in 2000 for production work under The Neptunes. Since then, their bond grew stronger as both artists became larger than life. Billionaire Boys Club no doubt influenced Jay Z's latest album, as the 13th song takes the BBC moniker. With this connection, there was no excuse not to collaborate on Pharrell's clothing line, thus spawning the MCHG t-shirts as a result. The graphic was produced by Japanese designer SK8THING, who put together an astronaut holding the Holy Grail in his hands. Both colorways are currently in stock at Billionaire Boys Club retail stores and webshop.
