Bump.
Went on a trip to the Funen island and found this fellow in a cute farmhouse antique shop for very little money, on the Helnæs peninsula.
Chronologically, there's resemblance say to Schumann portraits, and it's thus from the decades called the 'Golden Age' of Danish art. Probably around 1825-60.
Looking forward to try to perhaps obtain further background info about the portrait. There are colours and undeniable traits of brushwork, and possibly also drawing, but maybe it's a print that's been improved upon. If indeed it's all miniature drawing, it's extremely accomplished. It's done on some hard, bony, beige material, that has a couple of hard cracks, so it's not on paper or cardboard. Strange. Some sort of porcelain??? There's a glass cover; removing it will tell more about the technique, but I'm hesitant to do it, at least right now.
Also, there are colour disfigurations in the lower left, where a table corner is pictured.
The friendly, but not so informed dealer (on this subject) wrongly suggested that it might be a photograph - but I corrected him.
The amiable-looking but also somewhat detached fellow (so far he's just called 'Olfert') holds a letter with a seal, suggesting some societal reward, or educational/administrative/personal communication ...
