Over time, the logo and / or the font color of the well-known lettering of the label Harthouse changed discreetly every now and then. Mostly these changes documented parallel changes in or around the label itself. For example, in Frankfurt the color turquoise was dominant, while in the Mannheim time the lettering was orange. The current color of the logo, since the label is based in Berlin, is red. This t-shirt shows the current red lettering.
