1936 Ovaltine premium from series of 12 issued for the months of the year. Top edge of this one reads "March-Wisdom." Top is inset with a beautiful faceted clear stone of aquamarine color. The 4 tiny brass prongs that hold the stone at its side all have missing luster and on close inspection surfaces are somewhat rough with corrosion. On two of the sides the corrosion has removed just a little bit of the surrounding brass luster. However, this damage is really quite isolated and the stone displays Mint and about 90% of the ring base retains its Mint luster. Overall we'll say Fine but vast majority actually displays much closer to Exc.
