PrincessMewMew had this post about how she had found one of these and she had never seen the Last Supper (can't remember what materiel it was on)
And I had commented that The Last Supper here is like almost in every Catholic home
I grew up with it on a carpet that was hung on the wall

So, when I saw it on your wall I had to alert her to come take a look
Hope she does :)
