The Design Museum at UC Davis is hosting “Rattled,” an exhibition of more than 100 baby rattles (many of them historic) from the collection of Lu and Maynard Lyndon, the founders and owners of Placewares+LyndonDesign in Gualala, on the coast in Mendocino County.

One of the earliest toys devised for children, baby rattles have evolved over the centuries into a variety of shapes and sizes. They are symbolic of how design responds to socioeconomic factors and cultural identity, and represent a design chronology of style, function, sound and materials.

The exhibit opened on Sept. 25 and continues through Nov. 20. There will be a reception and collector’s talk at 6 p.m. Thursday, Oct. 1. Admission is free.
