If you want a t-shirt with a GPS airport code oval on the front and a map of the Galapagos on the back, here’s a version I put up on Zazzle.
The map is based on one in Charles Darwin’s Journal of Researches. I colored-in the islands a bit so it looks better on different color backgrounds, plus updated the names of the islands to the modern, Spanish versions.
Redbubble will put print it out and send to you on t-shirts, mouse pads and endless other objects. FYI, the mug is different and features two (2!) maps: one with Spanish names, the other with English names. That combination is handy if you regularly read both Darwin-era books and modern-day journal articles about the Galapagos.
