back in the old days of GP............ i forget exactly how submissions went down but it was pretty easy for the lazy and/or drunk to leave off a lot of the information. i think i've lost a few posters to the GP conversion void. such is life.
not sure. i think we get the fillmore prints in the week after the show. write email@example.com ( ironically not my direct email ) and one of the friendly staff should be able to answer your question.
