If you are a gnome collector and a stamp collector then it would make a certain amount of sense if you decided to collect stamps with pictures of gnomes on. To the best of my knowledge the UK has never released any official stamps with gnomes on them but there are plenty of countries that have.
In September 2016 (in time for Christmas) Denmark released this series of stamps designed by Gustav Mårtensson & Peter Møller (Illustrator). None of them are worth much more than the original face value at the moment (which is about one pound) although the one with the Gnome (Nisse in Danish) dancing seems to be a little rarer.
Below is a series of Dutch gnome stamps released in 2008 entitled Gnomes in Dutch Literature
‘De Kabouter’ (Dutch for the gnomes) refers to The Gnomes book by Wil Huygen and Rien Poortvliet which everyone knows about. Paulus de Boskabouter (Paulus the Wood gnome) was originally a newspaper comic strip that went on to become a series of books, a radio series and a television puppet program. Pigglemee is a series of children’s picture books written by L. C. Steenhuzen which were used to advertise Van Nelle coffee. Wipneus en Pim (Snubnose and Pim) was a children’s book written in 1948 by Bruno van der Made, eventually there were 40 books written about the pair of gnomes, ending in 1985 with prince Snubnose becoming king. The last one Pinkeltje (known as Fingerling in English) was a series of books written by Dick Laan which were later made into a film.
Below are two smaller sets of Swedish stamps clearly intended for Christmas.
This gnome-like garden sculpture and a blue ribbon was issued by Finland in 2013 to raise money for charity. The stamp cost €1.20 of which the ‘extra’ 20 cents going to support prostate cancer awareness.
No Doubt there are many other stamps out there with a gnome theme. In England we used to be able to make our own stamps by uploading an image to the royal mail website. This ‘personalised Smilers®’ service has now been stopped, presumably on the grounds of cost. The Americans still have a similar system which they have outsourced to companies like zazzle. Some of these are pretty good but I have not included any because although they can be used they are not what most stamp collectors would call ‘proper stamps’.
