Hair museum

Located in Capopadocia -

[T]he museum was started over 30 years ago, when one of Galip’s friends had to leave Avanos, and he was very sad. To leave him something to remember her by, the woman cut a piece of her hair and gave it to the potter. Since then, the women who visited his place and heard the story gave him a piece of their hair and their complete address. Throughout the years, he has amassed an impressive collection of over 16,000 differently colored locks of hair, from women all around the world...

Twice a year, in June and December, the first customer who comes in Chez Galip’s shop is invited down into the Hair Museum to choose ten winners off the walls. These lucky ten will receive an all-expenses-paid week-long vacation in beautiful Cappadocia, where they will get to participate in his pottery workshops, for free. This is the artist’s way to give back to the women that helped him create the unique museum which bring in new customers every day...

And very clever marketing, I would say.
