We most frequently use Red River Paper's Ultra Pro Gloss 2.0. It provides the most vibrant colors and has just the right amount of gloss. We also experiment with new paper options for select prints, so look out for that in the future!
Each print will come packed in a 13x18 Stay Flat envelope that is reinforced with thick chipboard in order to protect the print during all the bumps and bruises of the shipping process. Tubes are available by request but I am sure you hate flattening out your posters just as much as we do.
I work and live out of Atlanta, GA but travel to various conventions and artists markets throughout the year to sell my artwork.
