A blue whale penis. Pretty sure this photo was taken at the Penis Museum in Reykjavik in Iceland which is exactly what is says on the box. Includes a severed member from every species that inhabits Iceland and it's surrounds. (Including human).
I stayed in that hotel last time I was there. Very modern with the right amount of comfort without overdoing it. Photo of one of the sides from another angle. Room pics are on a seperate HD somewhere. Very retro.
It's actually just outside Amsterdam and a 20 min train ride into the city.
