9 by 12 plate cameras like that were pretty common 100 years ago, not so much now. GIs brought a lot of them back from Germany after World War II.
The biggest problem you would have if you wanted to shoot with it would be finding plate/sheet film backs -- or a roll back -- to fit it. Every maker of those cameras had different measurements of backs and roll film holders, while available, don't fit interchangeably either. I have an early camera similar to that that had a roll back on it and it doesn't fit on any other plate camera I've come across.
Vario is the type of shutter, probably made by Agfa. It is not the name of the camera's maker, which might be impressed into the leather on the camera body somewhere, or might not. There's a lot of pretty generic cameras like that floating around. Could be anyone -- Zeiss, Voigtlander, someone else.
It takes a certain amount of dedication to use one of those -- finding plates, cutting your own film if need be, etc -- and from the looks of it, that camera is pretty rough. Bellows leak light?
Assuming all is well and you can find plate holders (originally made for glass plates, often with inserts to hold film) your best bet might be to use it to make paper negatives, using standard photo paper, which you can then print from or scan and reverse in photoshop.
Cameras like that make wonderful bookends, too. Just saying ...
