Ben has a wonderful knack of these tours, mixing history, design and a hint of psychogeography. There are a few types (sorry) of tours:
"Digbeth Type Tour: Exploring use of typography and handwritten letterforms in industrial Digbeth side streets. The area's history revealed through its use of type.
Baskerville's Birmingham: the history of Birmingham's most famous typographer, John Baskerville (1706 – 1775). Artifacts, locations and type specimens associated with Baskerville will be visited, around Birmingham City Centre.
Blue Plaques tour: The history of Birmingham and of the Blue Plaque itself: changing and improving designs, layouts, type use &c. The tour also covers plaques other than Blue; many forms of wall mounted commemorative texts around the City Centre.
City Type Tour: Birmingham history as shown through its typography. Civil, monumental and commercial use of typeforms will be explored in Birmingham City Centre." [link]
