circa. 1780 Beehives representing industry under a protective roof outside a blacksmith's shop. From Bowles's Moral Pictures: or Poor Richards Almanack Illustrated.
The inscription says:
'He that hath a trade hath an estate. At the working man;s house hunger looks in, but dares not enter. Industry pays debts. while despair increases them.' -Benjamin Franklin, Poor Richard Improved, 1758
The Poor Richards Almanack was founded by Ben Franklin in 1732 under the name of Richard Saunders; he continued to publish it for about 25 years. Combining entertainment, moral instruction and practical information, Poor Richard's Almanack proved both popular and profitable, and as the existence of this print attests, many of Franklin's maxims were passed down to later generations as sage advice for young people and are now classic Americana.
