Hi, I have some questions about some Quaker State Oil signs I just found. First I'll tell you some info about the signs. They are metal embossed signs 34" x 70" basically identical except for the numbers in the lower right hand corner and two of them have reflective letters and the other two have plain white paint on the letters. They all have Quaker State Oil Refining Corporation in the lower left hand corner. Two of them have G-95 in the lower right, one has G-55 in the lower right and one has Grace Sign Company, St. Louis, MO 13 in the corner. One of the G-95 signs and the Grace Sign Co. sign have reflective paint on the letters. I guess my biggest interest is the age of the signs but any info will be much appreciated by me, my two sons and my brother. Thanks, Ken
