Vintage Marionettes

My daughter and I purchased these at an estate auction yesterday. They appear to be hand made. Each has a T-shaped control bar made from paint stirrers from the Jewel Colorizer company - which tells me that at least the sticks date from the 1960's, in the Chicago area. And that's all I know about their provenance.

The faces are papier mache, and the bodies are wood. The hands are carved somewhat crudely. The strings appear to be original - some are down to a thread or two, and others have snapped and been retied.

Does anybody have more information on these, or can tell me a ballpark value (if any)? My daughter wants to play with them but on the off chance they are valuable as is, I don't want to risk further damage.
