NIKOLA TESLA HIGH SCHOOL – HK Official! Henry Kaiser in 1976 wearing his original Nikola Tesla High School tee. Henry ordered the shirt from a custom-lettered t-shirt ad in “Popular Science” magazine. Rather than being silkscreened, the shirt was made with iron-on transfer lettering, a relic from the early days of custom t-shirts.
