Caps from Akkordeon Slab in use for Oppumer Eiscafé, an ice cream parlor in Krefeld, Germany. This typeface was designed by Eduardo Manso of the Emtype Foundry. Like its sans-serif companion, Akkordeon, it comes in fourteen numbered styles of increasing width and weight. The sign uses caps from Akkordeon Slab Four.
Spotted in 2019 by @isoletters, who notes that this choice is a refreshing departure from Brush Script and other scripts that are commonly used on signs of German ice cream parlors.
