This is a lot of four vintage rulers.  Three are advertising rulers.  The McDonald's ruler is made of metal and is bendable.  It says McMetrics on it and was made in the USA.  There is a black plastic ruler that was a thank you from First National Bank and Trust Company in Centralia, Illinois.  It is from their 50th Anniversary in 1971.  It has wear and surface scratches on the front and back.  One wood ruler is advertising Norm's Corner Delicatessen, 1225 Hertel Ave, Corner of Traymore.  From research I see this is from Buffalo, New York.  It was made in the USA and has wear on each side.  There is a small piece of wood missing on the back side edge.  Finally there is a school ruler with only inches on it, no centimeters.  It looks like it belonged to Mary Cosey in Room 3 which is written on the back.  It has marks here and there.   All are sold used as is.
