The cardstock is very thin. I will guess that it is a CdV from the 1870’s.
The Photographer was H. Krum of Throndhjem which I believe is a city in Norway. Perhaps one of my readers can translate?
Thanks for stopping by. Do come again:)
Update from That Norwegian Guy:
The photo is indeed from Norway. The language on the back however is Danish (which comes as no surprise).
Transcript (as far as I understand it): Modtag denne Erindring som rækkes dig af din Ven og ... ved Seminariet
Translation: Accept this memory that is given you by your Friend and ... by the College of Education(?)
født 4/8 48.
which means this Theodor was born August 4th 1848.
Update from the Archivist:
The last part of the inscription reads, "...accept this remembrance given you of your friend and contemporary [samtidige] at the seminary [or teacher's college]." (ved= by, or at)
