The Astronomical League offers posters for clubs to download, then have printed for display at their public events such as Astronomy Day. They range in size from 20 x 30 inch sheets to materials that can be mounted on tri-fold project display boards. Some are available in 8.5 x 11 inch format. These documents can be printed at a local print shop at a rate of about $0.75 per square foot for black and white copies. Please visit https://www.astroleague.org/outreach
