Nice sleuthing, Tobi! Lettergraphics may have had a few original faces, but the vast majority of their library consisted of clones and copies, some licensed, some probably not. By contrast, the alphabets shown in the lettering manuals by Lisa Beck and Eugen Nerdinger strike me as highly original. I’d assume that Lettergraphics sourced this one straight from the Alphabete book. I am not aware of another version, film or digital.
