MANY PEOPLE ARE INTERESTED IN VINTAGE DENIM.  I GOT INTERESTED IN IT WHEN A SAW AN OPRAH SHOW ABOUT 8 YEARS AGO.  I DECIDED TO BUY A VINTAGE DENIM BOOK AND LEARN MORE ABOUT IT.  I WAS AMAZED AT THE AMOUNT OF MONEY OLD JEANS COULD BRING.  I THOUGHT I WOULD RUN RIGHT OUT AND FIND ME SOME.  VINTAGE DENIM IS VERY HARD TO FIND.  IT IS GREAT TO KNOW WHAT TO LOOK FOR SO IF YOU DO COME ACROSS SOME THAT YOU KNOW WHAT IT IS.  THE BEST GUIDE I HAVE FOUND IS TO LOOK AT CLOSED LISTINGS WITH EBAY.  SEARCH THE HIGHEST PRICED VINTAGE JEANS OR VINTAGE DENIM JACKETS.  THE BOOK I PURCHASED WAS CALLED VINTAGE DENIM BY  DAVID LITTLE.  I BOUGHT IT OFF AMAZON NEW FOR 16.00.  I ACTUALLY SOLD IT FOR $100 ON EBAY 5 YEARS LATER BECAUSE IT IS OUT OF PRINT NOW.   THERE ARE A FEW TELL TALE SIGNS TO LET YOU KNOW THAT YOU ARE LOOKING AT AN OLD PAIR OF LEVIS.  ONE IS THAT ALL THE LETTERS ON THE LITTLE RED TAB ARE IN CAPITAL LETTERS.  HENSE THE TITLE THAT YOU SEE "BIG E".  ANOTHER SIGN IS THE COLOR.  AFTER YOU SEE VINTAGE DENIM YOU CAN PULL IT OUT OF A PILE OF 100 PAIRS THAT ARENT.  IT IS VERY DARK WITH LIGHTER COLORED FLECKS.  IT IS USUALLY A STIFFER FEEL.  ANOTHER THING TO LOOK FOR IS WHEN YOU TURN THE PANT LEG UP ON THE OUTSIDE THERE IS A SEAM THAT RUNDS DOWN THE SIDE OF THE LEG.  IF THERE IS A WHITE STRIPE DOWN THE EDGE OF THE FABRIC YOU MAY BE LOOKING AT A PAIR OF "REDLINES".  THEY ARE CALLED THAT BECAUSE THEY MAY HAVE HAD RED LINES RUNNING DOWN THE WHITE  EDGE.  THEY MAY STILL BE THERE OR COULD HAVE FADED.  THERE ARE MANY OTHER WAYS BUT THESE ARE THE BIGGIES.  I HAVE FOUND MANY VINTAGE DENIM ITEMS IN MY 7 YEARS ON EBAY.  I AM SO GLAD I DECIDED TO EDUCATE MYSELF.  MORE KNOWLEGE IS ALWAYS  A POSITIVE THING IN ANY EBAYERS LIFE.
