Here's the Gdrive link to a folder that contains different wheatpaste posters that you can place around the world. Make sure to do it LEGALLY;

The wheatpaste posters should all be 18×24 inches, 24×36 inches and 48×72 inch formats. Make sure to research where in your city or town you are able to put these up as SPX6900 holds no legal accountability for your actions.
Watching a tutorial on how to apply these will help you as you also need to get a paint roller and mix the wheatpaste glue.
