I made a couple of promo banners for the Romanian WLM 2012 campaign, sources are available to Commons and should be easy to edit/translate/reuse: https://commons.wikimedia.org/wiki/File:Afis_Wiki_Loves_Monuments_2012.svg https://commons.wikimedia.org/wiki/File:Banner_Wiki_Loves_Monuments_2012.svg
For easy license, all photos are made by me and were also submitted as part of WLM 2011.
