Gallery Sign collaborates with both national and international artists. There are two exhibitions each year, opening on the longest day of the year and the shortest day of the year. 

Gallery Sign is an outdoor gallery in the form of a sign outdoors at Dugguvogur 43, 104 Reykjavík, (on the corner of Dugguvogur and Kænuvogur). The works can be seen from the street so there are no formal opening hours.

Gallery Sign is run and curated by Birgir Snæbjörn Birgisson and Sigrún Sigvaldadóttir.
