Murale 8 panneaux l 8 pi x l 144 po de béton Kaia

On the far left of the mural there is a massive noticeable black curved line. It is in the drawing as well for the layout, but it seems like a mistake. I’m lucky that I do not have to use that panel, but the printers should re calibrate the drawing to remove the curved line that does not look right at all.
