Ashtray my grandpa used to use is still used by me.
LEICA M-P (Typ 240) + APO-Summicron-M 75mm f/2.0 ASPH.
This ashtray is the one I use in the living room. And actually this is also the one that my grandpa who passed away when I was about 3 or 4 and was the husband of my grandma I live with, used to use.
After his death, this one used to be used for guests visiting to my grandma's house that was sold couple years ago though, I was given after I started smoking. There's no longer that house as well.
But this ashtray is still here. As my favorite.
