Invader Motor Oil Metal Advertising Sign Vintage SUPER CLEAN/ LARGE For Sale

An old Mechanic in my neighborhood is closing up shop and I just purchased this great very clean Invader Oil Sign.  He thinks it\'s been hanging on back wall since late 50\'s or early 60\'s.  Tried to find an example of this on line and couldn\'t find another one quite like it!  This was always hanging in the back of the garage, no light so the colors are super bright!  Shows a little wear in a few spots.....see photos but overall very nice!  Back looks mint!  Measures about 12\" across and 48\" tall.  He had a few other Invader items but pretty rough condition!  This survived because it was always hanging!
