Sarchí, Costa Rica - original ox cart taller (shop) worth a visit. In Sarchi town, see a hugely over-sized one on display. There's also a book on the history of these ox carts, specific to Costa Rica by Michael Sims.
Here is the traditional wheel painting that was done on the oxcarts in Costa Rica. The tradition lives on in the community of Sarchi. Each oxcart is handpainted and they all have individual and unique patterns.
