I’m simply starting this topic to see whether Anna will paste some info on this amazing banner face into this space to get the ball rolling.
I revived Motto only after I studied the rather poor scans to see whether it might get close enough to the original for usability. I think my efforts were decent, but there remains some doubt as to the details in some of the more inscrutable glyphs.
24 pt. Motto is currently cast in metal by Skyline Type Foundry from matrices that were, I believe, manufactured from surviving original type (probably either by Charles Broad or Andrew Dunker). It may be worth it to pick up a fount of Motto from Sky Shipley and print new specimens of the characters for scanning.
