"Hinamatsuri in Hiketa", by mars2015.

Butler's Maridon Museum has a Hina Matsuri Doll Exhibit now through May 3rd, in addition to its regular exhibitions of Asian art. March 3rd is Hinamatsuri (雛祭り) in Japan, Girls' Day, and is commemorated by a series of dolls, says Wikipedia:

Platforms covered with a red carpet are used to display a set of ornamental dolls (雛人形 hina-ningyō) representing the Emperor, Empress, attendants, and musicians in traditional court dress of the Heian period.

And the museum writes:

When a little girl is born in Japan they usually are gifted a set of Hina Matsuri dolls. These dolls are to be put up and taken down on March 3rd. If the dolls are not taken down at the end of the evening it could me bad luck for the little girls future.

This Festival is also called "Momo no sekku (Peach Festival)" because of the peach blossom season on the old lunar calendar.

The museum is located at 322 North McKean St in downtown Butler (map), and is open Wednesday through Saturday from 11:00 am to 4:00 pm.
