I've been out of sync in the creative department lately so I haven't come up with anything worthwhile for posters but yeah...
Sorry if it's not what you expected, but I gave it a shot. I see you do some gfx yourself so maybe you can add any slogans or dates if you want.
On a separate note, I have a couple more BTB poster requests to fulfill, but I should get those done soon. Other than that, I'll fulfill more requests as soon as possible, but I can't really tell which requests are done or not since there seems to be requests done via private messages as well. Maybe just send me a rep message if your request is here and needs to be done, and I'll get to it when I can.
