Found your site while researching this same subject for a Facebook group on Peoria. I have a postcard of a baby elephant standing with a trainer, the back of which is printed with the following:
"A recent addition here at Glen Oak is Dona the Baby elephant She's learning some tricks for her very own show, a really outstanding event. Glen Oak Park Zoo Peoria, Illinois"
The postcard was never mailed and there are no dates on it. The name is spelled "Dona" on the card, not "Donna". The man in the photo is youngish and I don't think it is Joe Frisco. I remember seeing this elephant at Glen Oak Zoo, but don't think she was there for more than a couple years. //Anonymous
