This is the 1959 quotation book which belonged to my dad. You can see a piece of paper tucked inside the cover and this is one of many pieces he added with his own favourites. An example of this would be:
"Knowledge is understanding a tomato is a fruit, not a vegetable. Wisdom is not putting it in a fruit salad."
My dad's interesting relationship with humour is better illustrated here than in anything else he left behind.
