I'm willing to trade this for the Mercator OP in black or red but also for a print with a cloudy sky theme!
Here's my wishlist http://imgur.com/a/L6Lkw If you have something else with a cloudy sky, please send me a message!

Good condition, bought second hand and I see no flaws.
No smokers or pets in household.
Size in reference link.

Shipping from Finland is fairly pricey so I can consider flexibility.
For Europe it varies from 22,90€ to 29€. For US it's 40€.
Visiting Prague next month so I can consider shipping from there if it's cheaper :)
