Graber Realty Buy Graber vintage advertising real estate realtor pin

Here I have a vintage advertising pin. It says "Hi Neighbor Graber Realty Buy Graber" and has 2 like little eyes to remind me of a smiley face type design. The pin I am estimating to be from the 1960s or earlier. I honestly don't remember when they stopped making the pins out past the edge of the pin because you could get poked by it. The pin has some scratches, and wear marks on the front which can be seen in the pictures. The front of the pin is 1 inch in diameter. A neat old advertising pin to add to a collection.
