I have been racking my brain, trying out all sorts of letter combinations, but I can not seem to make out what is the original meaning of this sign. I can see the letters for 'yellow' and the background of the sign is yellow, but that may not mean anything. It may be quite simple or even not English, I have considered that. If anyone knows the answer please tell me so that I may sleep and not see this sign in my dreams.
Thank you so much! I notice that it is easier to make sense of the sign in your link because they have the 'W' in white rather in black like in the post. I imagine they realized that it was a bit too unintelligible and changed it.
Looks to say "Yellow Edge" from the top down and bottom up. So yellow is in there twice. I believe the other commenter is right that it's the Yellow Edge gallery.
