Mondo’s second round of posters remaining from MondoCon go on the web Tuesday! Be the initially to know when your favorite things are going on sale and cool events in your location. The resurgence of comic book popularity in the 1960s led to the mass production of comic book posters in the 1970s and onward. Most posters are printed on a single side and left blank on the back, the far better for affixing to a wall or other surface. Pin-up sized posters are generally printed on A3 Standard Silk paper in full colour.
