Are wind-up Dick Tracy squad cars and Barbie dolls barometers of our culture? And why did people actually pay for a Pet Rock?

Shannon Voirol, exhibit developer for History Colorado, talked with Colorado Matters host Ryan Warner about toys and their historic -- and nostalgic -- relevance. Starting June 13, History Colorado will feature "Toys of the 50s, 60s, and 70s," an exhibit that runs through Oct. 4.
