It's only a sweatshirt with Tibetan on it!
བཀྲ་ཤིས་བདེ་ལེགས bkra shis bde legs - the Tibetan greeting often written tashi delek.
This shirt is advertising the Yak & Yeti restaurant in Disney World's Animal Kingdom. The "Asia" area of Animal Kingdom has decor meant to evoke India, Nepal and Tibet. This includes a lot of signs in Devanagari, although I couldn't make sense out of a lot of them.
आनन्दपुर दूरसंप्रेषण - Anandapur telecommunication
अब आगे कहाँ - where next
कोका-कोला - Coca-Cola
They're even throwing some Ranjana up there! I don't know if you would ever see Ranjana on a public telephone sign, but I love how the Disney imagineers know that this script exists and decided to use it.
This is Nepali!
