I use mine for a key holder, but it is actually an antique country or department store sales ticket holder. Handwritten sales tickets had a hole at the top and then through the day as the sales gradually accumulated they were hung up until the end of the day when they were then totaled.
OMG just jogged my memory you are so right I got it as a key holder but had forgotten they were used for sales tickets thanks so much for the clarification on this
