Frogs of the World Challenge

Received from and sent to Eric Bruth (France), for his project Frogs of the world challenge:

The frogs of the world challenge is a project I launched to get, from as many countries as possible (and as many place in the world as possible), a cover illustrated with a frog, the flag of the country and the word frog in the language of the country.
This page presents the current result of the challenge. If you want to help me on this challenge, please contact me by email.

Maybe can you help him?
