Coca-Cola Wooden Ruler

Q I have an old wooden ruler with ”A Good Rule, Do Unto Others As You Would Have Them Do Unto You” printed on one side and ”Compliments The Coca-Cola Bottling Co.” printed on the other side. Any information you could tell me about it would be greatly appreciated.

A Rulers like yours were popular advertising and promotional items given out by Coca-Cola bottlers for years. From 1925 until the early 1960s, they were distributed to schools throughout the United States. Because they were made and given out in such large numbers, they are easily found and not very expensive ? about $5 to $10.
