This great photo of old phones translated into sheep at the Museumsstiftung Post und Telekommunikation in Frankfurt comes from Xavier Caballé’s Catalan blog. The sheep are by Jean-Luc Cornec.

The sheep can also be glimpsed in situ at the museum’s site (link above) in the upper panorama.

I found a Castilian photo too, but it isn’t quite as good.

Hat tip to Trevor.
