Just wanted to let everyone know that in my opinion the plastic 3' Diamond or square OK sign faces ran on ebay the last few weeks are repros. They are VERY nicely done - I bought one. Seller was very good about taking it back when I determined for myself I wasn't convinced it was NOS. Several different sellers out of the upper midwest are offering them. I have had multiple original signs like this over the years and had a couple originals here to compare the "new" one too. As I said -they did a great job. Biggest difference I can tell you to look for is the depth of the mold on the OK letters themselves - new sign is more squared off and deeper - original is more gradual and rounded. Unfortunately, no date, has the Registered trademark just like original, great color matches, etc. I believe many people will have a very hard time telling them apart without a nice original side by side. As always - buyer beware.
