These were all originally purchased, I'm guessing around 1960-1962 or so give or take and owned by an 89 year old man that hadn't used these in years and had recently passed away and the relatives were cleaning out the house in preparation for an estate sale.
They said these were found inside in the basement under a set of stairs. From the label on the box it looks like he purchased these from the old Dayton's Dept. store in Minneapolis which was the parent company that eventually became the Target Corp. Yes, at $9.95...I'll take a dozen please!
