"The 1968 Democratic campaign of Hubert H. Humphrey suffered from a lack of campaign funds, which accounted for the absence of the necessary campaign materials. While such staples as buttons and bumper strips were plentiful in 1964, the supply in 1968 was chronically short. Burdened with pre-convention debts, the Democrats were not able to scrape together the $100,000 needed to purchase the first order of buttons (designs for which had been in readiness for weeks) until September 23. Until that date, the national Democratic headquarters dispensed small paper stickers which said: “If I Had a Button, It Would Say Humphrey-Muskie,” until more expensive pinback campaign buttons were available.” From A Concise History of American Campaign Graphics 1789-1972, Dale E. Wagner, 1972
