When I worked at Little Earth Production (home of the Terrible Towel) in my native city Pittsburgh, I was given the opportunity to design several products and packaging.
At the time, competitors were already selling temporary tattoos but nothing in the metallic temporary flash tattoo category. Metallic flash tattoos were in high demand: people were wearing them at every festival. Beyonce was even seen wearing them! So, we sent samples off to the leagues for licensing purposes and were approved for sale.
I designed individual sheets for all NFL and MLB teams. They were sold nationwide in stores and online.
