Is it that these aren't out there, or people just won't let theirs go?
 

I've been looking for 1910 Obak slogans "Delicate Aromatic" and "Mais Paper Wrapper" for a while. I've been told by several long time collectors that these are only slightly tougher to find, if at all, than the others, though I have yet to see one of either surface that isn't trashed or entombed and costing a small fortune.

Looking for vg to vg/ex. Thanks for looking!

In my experience there are only a few backs scarcer than others. The 2 you are looking for aren't those and shouldn't be impossible to find. Also, pricing is relative. I would think 20-40 for a decent obak with one of those backs would be about right. good luck
