I will be traveling around several countries (in southeastern europe) later this year. And I'm worried about the language barrier.
It occured to me, that it would be cool if I had a collection of cards/photos/pages, one for each thing a tourist might need to ask for (e.g. hotel, campsite, petrol, restaurant, café, bank, etc.), and each page/card would have various photos/icons for that thing, and/or the translation of that thing into various languages written on it. This way, if you want to ask where a petrol station is, you could show someone the card that would have lots of photos of petrol stations, and immediately avoid the language barrier.
2 years ago while traveling around Basque Country, Spain, it took several minutes to try to communicate with an elderly local man that we wanted a campsite. Once he figured out that's what we wanted, he was able to point us down the road. A picture of a campsite/tent might have speeded things up a lot.
This sort of thing could be easy to make myself, but has anyone made it already? It would be easier than having to reinvent the wheel.
