a local antique picker called one day and asked if I was interested in a pile of these. They were invoice slips from 4 or 5 Southern Ontario bottlers. I took about 20 of them for a $1 each. I got Hamilton Beverages, Kitchener Beverages, Riverside Beverages (Brantford) and Coca Cola Kitchener. They are really cool pieces of history.Interesting, how on earth did you find this?
