Eisenberg and Sons Original

  I believe  I have found what  piece that  I have in the Eisenberg & Sons Original.   I spotted it when browsing on Morning Glory Antiques & Jewlry.   On page 5 Bobye Syverson has a 2000 book called Collectors Compas Jewelry with the exact piece of jewelry that  I have that's right on the FRONT COVER and it is refered to as  "DOLPHINS".  With me not knowing Eisenberg's pieces  I was referring to the piece as three fish.  I now need to find out if this is indeed authentic, which  I beleive it is because of slightly knowing the person whom  I bought it from and I beleive it to be either her mother's or grandmother's, and at  the time of the garage sale both households were being sold with everything inside because the land had been sold to a private developer and both houses were being tore down to make a new subdivision of expensive homes.  The woman's daughter sold me a box that was printed knotts berry farms and in it was full  of several TIFFARI - LISNER- SWANK and various unmarked ear clips and brooches 30's - 40's  and 50"s costume jewelry,   so YES,  I do believe this piece that I have is an Original.  I just need someone to let me know if this piece is rare, and the  price rang for what it is worth.  I maybe interested in selling it as well. Thanks
