Child Size Arthur Umanoff Chairs?

I found these 2 chairs at an estate sale for 10$ each. They look exactly like Arthur Umanoff designed dining chairs, but seem too small. The seat height is about 17", and the back is about 28". I found one article of information saying that in 1961, Arthur Umanoff allowed his designs to be used by Storkline Company for a line of childrens' furniture. He/They called it "little shavers" and got into some trouble for including a child-size bar, which Arthur later stated was intended to be a "milk bar." I'm wondering if these chairs might be part of that line. There are no labels, and I can't find any photos or other info on the child size furniture. Regardless, they are in great condition, came from a house that had a lot of other cool mid-century items, and were 10$ each.
