A new private museum, Marco. It is located on the 2nd floor of "D'Topeng Restaurant", Jalan Setiabudi No 10, Simpang Siur, Badung, Bali (you may ask the taxi driver, "D'Topeng Restaurant, Sanur" at Jalan Setiabudi). The formal name is "D'Topeng Kingdom Museum"....
If you don't mind, Mr Moderator -- Rick and David -- I would like to to share the link to the museum's site.
