Thanks Mitchell! Various different values, colours, and phosphor were issued with this image of a reindeer, fish (or animal trap) and whale from 1963-1970. These petroglyphs were made on granite slabs in Drammen. Check out: Jenkin's 'Checklist of Postage Stamps Depicting Prehistoric Rock Art'.
Late usage? 40k from 1968 and 100k from 1970 on 1977 postcard.
