This looks like a well tasty show: Designs on Delivery is an exhibition of posters from the General Post Office (GPO) from 1930 to 1960, courtesy of the British Postal Museum & Archive.
The show starts today at London College of Communication (LCC), featuring work from a range of top designers, including Tom Eckersley's stark warning about packing parcels carefully (below).
The image up top is Action Stations: Saving Is Everyone's War Job (1944) by FHK Henrion - check out more images from the show in this Guardian slide show.
It looks like a fantastic collection of work, and stands in stark contrast with the current stuff being churned out for the dire 'People's Post Office' campaign.
The show runs from today until 4 November at the Well Gallery at LCC, Elephant & Castle, London SE1 6SB - directions here.
