A friend of mine recently purchased a silver vase with a very elaborate corinthian campus leaf motif on it. On the bottom of the vase there is a stamp that says I S C (which I thought would be for International Silver company), but each letter is in Old English style text (which I couldn't find on any of the pictures of International Silver company marks). Next to the letters of the company is a bust profile of an Eagle. Below the mark is the number 822 and below the 822 it says Patent No. that says either 72882 or 12882 (it's rubbed off a little bit). Any information would be really really helpful! Thanks!
A search of the US Patent Office Database indicates that the patent was assigned to International Silver Company. The designer of the ornamental pattern on the Vase was Ernest T. Beck. The Patent was granted June 21, 1927
