I created this handy collection of all original GmTower posters (I extracted them from the addon files) so you can use them in your condo using those fancy new canvasses.
You can find the collection here: http://florens.be/tumods/gmt_posters/
Just choose one from the list and
copy+paste the URL into the canvas stretch it to the right size with scale x and scale y and choose poster for shape. Hope you like it, feedback is appreciated. If you want the image with borders on the side so you don’t have to do x and y scaling change /files/ to /files2/
