To continue, as for the condition of the green, 5-Pfennig, German South West African definitive, it's in fine shape! The S.O.N. cancel from the Omaruru P.O. is pretty nice, but a bit light/faded/smudged in some areas.
Lastly, as for the condition of the post card, it is pretty good for something over 112 years old It's pretty clean. There is a small tear in its bottom, left corner(from the front). There are also a few scuffs on the front. Noted imperfections aside, this is still a nifty piece of German South West African postal history!
