I found this poster on the UNESCO website. It is a runner up for the 'Languages Matter' competition. This poster says that it is based off of the Language Family Tree graphic and reflects some of the Millennium Development Goals and Education For All Goals. This piece definitely does reflect the 'family tree' aspect. It also looks like it has a retro style, which might make a reference to the Partridge Family (a family and bird reference).
Here is the link to the poster:
