T-shirt Design Brief
We need a t-shirt design for a YouTube adventure series called 'Josh's Epic Israel Walk'. The shirt will be given to people who have supported our successful crowdfunding campaign, and we will also sell a limited edition run as merchandise (to recoup costs).
This winter, my partner Josh, a tour guide by profession, will hike the length of Israel, and film the entire journey, documenting the trip as a series of YouTube videos along the way. He'll be following the Israel National Trail as as the basis of his hike, but will also be taking detours to film as much of the country, it's archaeology, culture, and landscape as he can. The trip will take around 4 months and will take him from the borders of Syria and Lebanon through the desert, to the Red Sea.
Josh's signature look is his cowboy hat, which gets him likened to Indiana Jones quite often by the people on his tours. We'd like to play off this theme with an Indiana Jones-inspired design, using the font from the films' posters. I've also had a look through some of the old posters and found one with the silhouette of Jones depicted as the opening to a cave, looking out across a landscape. Something like that might work really well.
I've attached the film poster, and also a selection of pictures of Josh and of the landscape he'll be traveling through for inspiration. We'd also like the three stripe trail-mark of the National Trail to feature on the shirt somewhere; if you can work it into the design, all the better
