Any 18 x 24" poster will be processed by Whitney Waddell Designs then sent to an off-site printer for actual printing. I do not keep backstock of these and to keep large format print costs down, I process all 18x24" orders once per week only.  Please allow 2-3 wks for processing, printing, and shipping. If you need it sooner, please contact me directly and I'll what I can do!
