Guidance on how to mount this

Wife and I made this large lego mural out of all of our botanical sets. Back of it is just a copy and paste of any of the mural sets. All together this thing probably weighs 20-25lbs. I've seen others like this online and didnt know if anyone had any advice for mounting this onto a wall. Thank you! submitted by /u/WittyRound [link] [comments]
