The box with the "Q" in the background is from QVC aka "The Home Shopping Network". It's not a coded message, it's a wingnut (or spouse) with a shopping fetish.
Yes I can see the kids with the LGB shirts. It's an awesome picture. However, the Q box has nothing to do with any of that. You're trying desperately to connect two unrelated things. Why?
Eye roll all you want but it won't change the fact that you can clearly see its a QVC box in the full resolution image. You're misleading people.
