I'm afraid it was there at the beginning of the year, at Fotografins Hus.
There is bound to be something worth seeing on show at that time, as well as all the Christmas fa-de-la. There isn't a good online listing of photography shows, although if you can read a bit of Swedish
www.fotosidan.se are as complete as anything.
The mainstream photo magazine, "Foto" usually has pretty comprehensive Stockholm listings, but they miss all sorts of stuff elsewhere in the country. Their website is a useless mess, but if you pick up a copy when you arrive it'll make a nice souvenier. Much better than Pop Photo, but still aimed at enthusiast/club members.
