Poster Packaging

Posters are rolled into a tube or toblerone to prevent damage during shipment and will need to be uncurled and flattened once delivered. We recommend placing the poster on a hard flat surface (such as a smooth tabletop), and placing heavy books on either end for several hours.

Poster Frames

Framing is the best way to preserve your poster and we recommend using a minimal, mat-free frame in either a black, white or silver finish—see example below. It’s preferable to find one with acid-free backing. The frame size should match the desired poster size (12x18 or 24x36 inches). Note that all of the prints incorporate a quarter inch bleed to account for standard frame overlapping.
