Four of these are 2.5" and the oval is 2-3/16". These were all issued in 1979 in protest of the Carter administration farm policies. Three carry the name of the group. One was used in the protest wherein the farmer's drove their tractors into Washington and this reads "Washington D.C. Or Bust/A.A.M. Tractorcade/Winner, So. Dak. January 79." Couple of the blue letters are light on this one as made and the one reading "We Need 10.5% Not Peanuts" has tiniest bit of color bleed. All are essentially Mint as issued. These are from the Marshall Levin Collection and come with Hake's COA.
