There are all kinds of events taking place in Bangkok all the time, and yesterday, it was the Tattoo Festival at the MBK shopping mall.
You can find lots of tattoo artists in Bangkok, and actually in all of Thailand. Not just the modern tattoo as here ih the photo, but also traditional tattoos that have spiritual purposes, and that are said to sometimes even have magic powers to protect a person or bring a special fortune unto him.
The most popular example was actress Angelina Jolie who got tattooed by such a traditional Thai tattoo artist and later got high-paying movie roles that furthered her career even more. Ever since then, that tattoo artist has also become more and more popular and famous. But you can also find many Buddhist monks in temples who do these kinds of spiritual tattoos.
