2-1/8" without backpaper but with name of maker W&H on the curl. Gorgeous color showing product container of "The Best Jar Of Butter In America." With a tag hanging off the lid reading "First Premium National Butter Exhibit 1896." Surrounding rim text reads "Star Brand/The Butter That Made Minnesota Famous." The jar's lid includes numerous gold medal designs and names the company as "Milton Dairy." Left side has couple of air streaks under the celluloid that show very little and mostly just in reflected light. No stain and high gloss. About the third we've seen.
