In prehistoric days, cavemen used to eat a simple diet of nuts, fruit and honey. Taking cues from this “Paleolithic diet,” Caveman Cookies makes its national debut. The all-natural cookies are made with only four or five ingredients and are gluten-free, dairy-free and contain no refined sugar or preservatives. To depict the caveman ethos, each package features an illustration of a caveman rubbing his belly and wearing a lei for the tropical variety or ear muffs for the alpine variety. Before finalizing the logo, nine designs were crowdsourced, and the brand ended up going with the majority pick.
