1.75" with W&H backpaper shows freezing soldier with wind blowing his hat off as icicles hang from his rifle and nose. At center is frozen spigot and right is an anthropomorphic thermometer reading zero degrees. Text is "On Guard In The 'Sunny South'." This is the Collectible Pin-Back Buttons 1896-1986 photo example in the Spanish American War section item #131. Couple tiny cello bumps but of no consequence. Glossy, NM. We know of just three examples and the other two are damaged. Originally in the Joseph Stone Collection, the basis for the 1986 Hake book. Rare.
