The one in the photo is an original I bought out of Burns & Harris in the Nethergate in the mid 80's. I've had it all that time and it still has loads of ink in it. I got it for doing BLOOD SPATTER in my cartoons, but me not being much of a gory person probably explains why the pot today is half full yet!
You can still get Quink these days, but this particular jar & packaging above is now considered "vintage"..!!
