Not that the postcard was sent to me from Mexico! It actually came to me from the USA thanks to the Alphabet RR in the Postcrossing forums. The caption for the image says:
A villager drags an obstinate pig past a vibrant Tlacotalpan house.
Acording to good old Wikipedia: “Tlacotalpan was chosen as a UNESCO World Heritage Site in 1998 because the “urban layout and architecture of Tlacotalpan represent a fusion of Spanish and Caribbean traditions of exceptional importance and quality… Its outstanding character lies in its townscape of wide streets, modest houses in an exuberant variety of styles and colours, and many mature trees in public and private open spaces.” (UNESCO, 1998.)”
This picture certainly shows the vibrant colours!!
It is from ‘The Travel Book; A Journey Through Every Country in the World’ published by Lonely Planet.
