When I was still living at my parents' house my entire bedroom was pretty much covered with DT posters. It was pretty ridiculous.
Old WDADU poster (w/ Charlie), I&W Booklet poster, DTIFC poster and LSFNY Poster -
James LaBrie poster (upper right) -
Super duper ginourmous SFAM poster -
Awake Flag and Transatlantic Poster -
And some others.... (WDADU, I&W, Awake and FII album covers and a couple other random ones) -
