Great find in the back room of a hardware store I frequent!   Very old doorbell button, with room for a name underneath.  Measures 2-3/4" x 1-3/4".  In original box and has the 3 little nails to install.  I have several to sell...so buy one for your front and back door.  I will combine shipping. 

I found a bunch of other great stuff at this hardware store....a lot of decorative switch plates and some lighting.  Check my other listings!
