Manufactured Rubber Company stock certificate 1930's

Tremendous vignette of female Justice seated and flanked by male and female classical figures.  Unissued but circa 1926 from issued examples.

Very nice automotive and tire collectible.  Company processed reclaimed rubber from tires of early automobiles. While some reclaimed rubber was burned for fuel, the attempt to remanufacture tires was not successful due to the chemistry of vulcanization. Company went bankrupt in 1936, no doubt a victim of the economy and the poor business model.
