It’s hard to see here but behind all the greenery is a bell jar with astronauts and rockets inside (gifts from his boyfriend) and a diorama of the moon landing. When I asked Mattan what appeals to him so much about air travel, he thought for a minute. “I’m very much a dreamer,” he mused. “I don’t like reality; I can’t calculate the tip at a restaurant. But I easily get drawn into a different world or visual language. Plus, old airline branding is so strong. It wasn’t super-serious. Braniff Airlines had planes in 10 different colors. I don’t want to be that kid who doesn’t grow up but at same time it’s important to have that playful aspect in everything you do.”
