It's hard to tell if a scarf is realy worn by Elvis. During the years there are a lot of fake scarfs been made. If you would like too bey a real scarf you must find people who has recieved the scarf personaly from Elvis. Or fans who can tell the history of a scarf, maby a picture.
If you would bey a real scarf these day's you have to pay a lot of many. If you look into the books and internet you find prices between $600,- and $2500,-. (US-Dollar) The price depents of the colour and if the seller is knowing the scarf is for real.
Hope you have some good luck with finding a original scarf, and let us know if you find it !!!
