Feel free to download and use these materials as you see fit to make posters or wall displays. They are all dimensioned for A3 printing, but would work for A4 as well. Many printers have edge-to-edge/borderless/full bleed capabilities, but you might have to enable these in printer settings. Otherwise, the posters will come out with a white border.
The jpeg files labelled "no text" could be edited with your own text added. We use Badger font for titles, and Alegreya for paragraphs, if you're interested.
Character standies with no background might be printed out, then glued on card, and cut out for wall displays or free standing characters.
