Gulls Lane
In case you can't read the last word, it says "Get your seagulls in ure." I think 'ure' is local dialect for 'here', but I'm only half-Cornish, so that might be only half right...
UPDATE: Yep, seems I might well have been wrong. My fully-Cornish father, in fully-Cornish fashion, thinks Devon is probably to blame.
