'Y' turned out to be more difficult than I expected until I found a stamp depicting a roof boss from a church within 40 miles of where I live.
|Great Britain - 27 November 1974|
The boss from York Minster represents The Adoration of the Magi.
I had to resort to a tourism/sightseeing stamp from Yugoslavia for my second stamp.
|Yugoslavia - 8 July 1972|
There is a church on this stamp as well. However I have not established its exact location.
