Sent my way by Marcin Wichary on Twitter is this rather adorable little illustrated map. It’s from the front page of a leaflet issued to introduce new – and quite substantial – changes to routes in San Francisco, moving from a radial pattern that centred on downtown to more of a gridlike pattern covering the whole city. The changes also introduced the concept of timed transfers at some stations to eliminate long waits for transfers.

The illustration is simple but charming, with a rather lovely Sutro Tower right in the middle and a modern (for 1982!) streetcar emerging from the Twin Peaks tunnel below – the problematic Boeing-Vertol LRV.

Also of note for all the pedants out there who insist that “Muni” has to be styled in caps/lower case as it’s short for “municipal” and not an acronym – Muni itself styled it as all-caps back in 1982!
