These custom kokeshi dolls are a part of a display at the Japanese American National Museum called "Kokeshi: From Folk Art to Art Toy." They're currently on sale at the JANM website, although delivery won't take place until after the exhibition concludes.
The Japanese American National Museum kokeshi doll collection consists of the work of 100 well-known contemporary artists. They range in price from around $200 to $700 and up.
Implications - While the dolls look adorable enough for a 5-year-old, they are actually sophisticated pieces of art. Don't let the colors trick you into thinking they are of amateur quality as they are actually highly coveted pieces.
