Pieces from the great Janssen Collection are exhibited at the Musée d'art et d'histoire of Geneva from the end of October to late April. From what the press release says (go here for the english version), it covers the whole of America from Alaska to the south of Chile. I should be able to confirm pretty fast as I intend to go and visit tomorrow since the entrance is free on every first Sunday of the month and there's gonna be a conference (the title: Elites and power in ancient Peru). If I can, I'll take notes and post them here. More conferences will happen while the exhibit lasts, and hopefully, I'll attend to a few of them. I'll keep you all informed.

I doubt I can take pictures though, as you usually can't with temporary exhibits, but you can see a few pieces on the museum website here
