This hanger is 192 feet tall. Let’s guesstimate that the words “Air Museum” are roughly 2/3’s of that height (given that they’re set on a curve and likely appear smaller than actual size). That puts each character at roughly 128 feet tall. Converted to inches, that’s 1536 inches. Converted to points, “Air Museum” is set to 110,592 point Helvetica.
