- A postally unused 1960's Photographic postcard published by Kenneth E Ruth of Ashburton which is entitled ' Princetown Dartmoor 1963 ' & shows a view of the entrance to Dartmoor Prison one the edge of Princetown on the Dartmoor during the ' Big Freeze 'of 1963 one of the coldest British winters on record. The Postcard is in good overall condition with a tiny amount amount of corner / edge wear along with a couple of other small light / faint marks mainly on the reverse as one might expect, including a very faint rubbed out pencil mark ( we assume the postcard was once part of a dealers stock ) Even so this does not detract from what is still an interesting 1960's Devon topographical postcard with possible Dartmoor / Princetown Social History interest ? see scans.
