Thomas Guernsey Dairy Clarendon Hills Milk Bottles

I have milk bottles from the Thomas Guernsey Dairy in Clarendon Hills, Il. --they are all square one quart size-- the street address is 452 Park Ave. other side of bottle has saying- "You can whip our cream but you can't beat our milk". I believe these bottles were used in the 1960-1966 years mostly before the half gallon becme more common. -- I am selling them for $20.00 each shipped. If you would like more than one they are $10.00 each plus shipping. I can combine the shipping for a better price. Thank You
