Tingatinga paintings originated in Tanzania by the artist Edward Saidi Tingatinga in 1968.  His work consisted of bright, bold colours, simplistic designs, inspired by his surroundings. Tingatinga taught six painters his techniques for painting, using bicycle paints. He lived a short life, to the age of 35.
After his death, those six painters who learned about his painting styles and techniques taught many others and the style spread across the world.
Tingatinga paintings can be described as both naive and caricatural, humor and sarcasm are often explicit.
Today, “Tingatinga” is the Tanzanian term for this form of art, known mostly in Tanzania, Kenya, Norway, Sweden, Finland, and Denmark.
