Here are scans of two more original and unused Ruskin postcards:
Walton Street building. I imagine this one dates from before the first world war as on the the reverse is printed ‘Oxford, Ruskin College – New Buildings’ which were new in 1908 I think.
The Rookery. This is a glossy card which could date anywhere between the 1930s and the early 1960s. The reverse has printed: ‘Photograph: B.J. Harris – Oxford’
