Cosplay Assistance

As the title says, I'm making a cosplay of The King in Yellow. With a very unique twist I've yet to see anywhere, (and no I won't be sharing yet) but I need as many versions of The Yellow Sign as possible! Personal takes on what it looks like "Official" (I know there really isn't one per-say) designs Anything that would look good or interesting etched, painted, or scratched onto stuff!

(I absolutely won't use anything without permission as that is flat out rude)

((Feel free to ask questions and maybe suggest ideas, I am still in the designing phase and need aide with how I want the Pallid Mask to look as well))
