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.
Not on wayback machine. Domain isn't even registered. But Yellow Edge Gallery exists. Nothing there about this sign, though.
Searching for "rowlart" leads me to http://rowlart.tumblr.com, an artist of a completely different style. The "Home" page excitedly states: "NEW WEBSITE HAS LAUNCHED! | Please visit... WWW.ROWLART.COM" This is our guy.
If we go back to Yellow Edge Gallery, we find that Rowland Phillips has exhibited there. This suggests that the sign is for his exhibition, so he would know about it.
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.
