Below is a ceiling treatment that looks like the old tin
ceilings.  It is actually raised pattern wallpaper as the base.  A
metallic copper paint was used to give it the shine of the metal
ceilings.  I love this ceiling, it is in my own home, I have had
people ask if it is real tin ceilings, this is an unbelievably
beautiful finish.  Scroll down for multiple close-up shots.
