Poster - Seed oils - battle of the oils (blue)A nice blue background for the 'Battle of the Oils' image. I'm thrilled with how these posters look and feel. They're printed on 200 grams per square meter (gsm) paper with a matte finish. They're sturdy, but they arrive rolled up in a cardboard tube so you'll want to flatten them out with books for a few days before putting them on your wall or framing them. The 12"x16" posters cost $7. 55 to make and $9. 59 to ship, the 18"x24" posters cost $3. 53
