I thought I would post the poster specifications for the conference here. Posters should be formatted as below (or approximate these measurements if printers do not hold A1 paper stock)  A1 841 x 594 mm 33.1 x 23.4in    Portrait orientation Posters will be displayed on vertical boards, secured with thumb tacks or with adhesive putty, so you can bring them to the conference rolled in a tube.  Most people create the posters digitally and have them printed, but, in keeping with the Graphic Medicine ethos, handmade/drawn/painted is OK, too.
