Where can I find a Doom(2) t-shirt?

I've been looking for a long time now and can't seem to find a Doom t-shirt anywhere...

I know ID had it in on sale in their store at their homepage but that store has been closed for a while. Any clues where I can find one, or when ID's store will be opening up again?

If I ever see one I'll let you know. Also, does anyone know where I can get a Doom II poster? I haven't checked Ebay yet but if anyone else knows of some other way please let me know.
