Sometimes patina makes the vintage soda sign that much richer.  If you know us, you know we love our rootbeer, and this Dad's Root Beer sign is just too good to pass up!!
 
This is a single sided Dad's Rootbeer Sign from the 1950s, according to our research.  The maker's mark on one corner says 'PM-4' which stands for Press Sign Company.  It's embossed, so the letters are raised on the Dad's logo and on the ROOTBEER.  This is a great size too.   The other bottom corner of the sign has the Union Label on it, and it has a rolled edge on it.  There are some dings, some of the edges you can see some waviness, and it shows it's age on the painted metal.
