Le Musee Imaginaire De Tintin 1980 Casterman Cloth

Hello: I have come upon a few Tintin titles and am wondering if anyone can help me estimate the value of the above. Thanks in advance.

7 months ago I bought it with a ridicolous price of 10 YTL (Between 6 and 7 Euros). I would go upon to a price of 30, perhaps 40 E for it, if the seller wanted.

I bought it in Istanbul and do not know the markets on the other side of Europe ( is it rare or not?), If you want to buy it, 40 E. is worth. If you want to sell it, I can say nothing except 'do not sell'
