Steph Posted March 6, 2009 Report Share Posted March 6, 2009 Any of ya'll seen these before? This is from the Aug. 1936 popular science. It has small "reflector buttons". "Reflector button" seems to be the industry's name for the individual mounted reflecting units like those in signs and auto reflectors. So some reflecttor buttons had marbles. But in this case the patent called for something more like "gems". Red ones. Link to comment Share on other sites More sharing options...
Ric Posted March 7, 2009 Report Share Posted March 7, 2009 Here are some Libby reflector buttons, with a screw base for easy replacement. They came in different colors too. -Ric Link to comment Share on other sites More sharing options...
Steph Posted March 7, 2009 Author Report Share Posted March 7, 2009 Those are cute. Thanks for posting them. Not surprisingly, there were stories of kids vandalizing the highway signs to get the marbles. Link to comment Share on other sites More sharing options...
