Posterage is a free poster studio with 175 generators. Make a city map, the night sky on a date, lyrics or a nursery name print from real star, street and elevation data, or your own words and photos. Edit colors, layout and wording on the poster, then download a 300 DPI JPEG. Sizes up to 12 x 18 in are free.
I wanted an easy way to turn a place, a date or a name that matters into a poster you can print at home, without needing design skills.
