A single Internet search turns up scads of results of Musk-associated merchandise, one of the most popular being Tesla's own apparel shop; in 2013 it was reported that the company pulls in millions just on jackets, shirts, and water bottles, and the SpaceX shop adds its own icing. A revenue stream like that is going to get some more personal company, which is why Zazzle also offers more than 100 different kinds of Musk-themed merchandise beyond that aqua clock, RedBubble has a couple of dozen offerings, Threadsquad throws in the singular "Elon Musk is my homeboy" tee and even Amazon rocks a poster page for the EV rock star. The man is also used to sell unrelated products. CosmeSys hair transplants, for example.
All this for a man who needs no promotion assistance. If the Model 3 does what's promised, we're guessing it will lead to one piece of merch that is so far missing from the pile: the Mighty Musk action figure.
