Obak backs
 

I've never noticed before, but there is a difference in the backs on T212 type 2 Obaks. The frame on top is different on some. Has this been discussed before? If so, sorry, I just have never noticed it.

Collected quite a few of the backs and never really noticed it. Not too surprising by some other printing differences we see.

I noticed it a couple of years ago too - got all excited, thought i found something new. Came here and found a thread where someone else had seen it also - there wasn't really any discussion about it though...

With all the Obaks I have had, it was just fun to notice something I had never noticed before. I was wondering if there was any type of system behind it, like if all the images from the 150 series had the same frame in the 175 series, and the new 25 would have the other. Has anyone seen any system to the two?

Just checking Old Cardboard it looks like the "Clean-Pure" back has both boarder types. http://www.oldcardboard.com/t/t212/slogans.asp
