On January 5, the Rolland Corporation Sent a Letter Offering

On January 5, the Rolland Corporation sent a letter offering to sell a new line of above-ground pools to Tibbets, the owner of Tibbets Leisure Center, at a considerably reduced introductory price. The letter stated that the offer would be good until January 20. When Tibbets received the letter on January 10, he immediately sent a telegram of acceptance.
