I have a picture of a reproduction and original to help anyone that does not know the difference. The top is fake with a date of 10-6-33 and grommets at the corners. The bottom one is real and dated with grommets in center at four locations. The real one is heavier but if you don't have both to compare to it won't help.
Pictured below, comparing the backside to show difference in grommets. The starred grommets are original on the left. Ted
