I dont know about 'The Temporary Sign' but near here ( Gods Country) there is a pub called
Letters Inn, whilst nother pub is called 'Bobs Smithy' because a local Blacksmith spent so much time propping the bar up there it was decided to rename it in his honour.

We have a pub called 'The Griffin' whose nickname is " The War Office' because of the number of battles that take place therein and for the same reason 'The Grapes' became 'The Blood Tub'
