i have not come accross any unbanded diplomas. most come with a very simple brown band that just says diploma. However, you might come accross some that have a pinkish orange hugh to them which are of the original blend and there are still some floating around out there. They are not as strong of flavorful, perhaps becuase of the blend or age I am not certain. Mostly you can find them in the camacho corojo ltd display that is a large diploma looking box with three compartments, each compartment holding a box worth of each size (diploma, 11/18, and 7/05) That is where I found mine. I bought the box becuase I dont like how the regualr diploma box only holds 18 sticks and if you smoke them like I do you need more. I gutted and modified the display box so it can only hold diplomas and now I can get 4 boxes in there at a time. I will take a picture when i get home and post it tomorrow from work. Back to the original point though, I am not as big a fan of these older ones but I think I only have 7 left. I think smoka has some too.
What I am really excited about from this line are two things. The new liberty that is coming out in a few months. It is the same size as the diploma and is supposed to be just as strong and made with lots of corojo tobacco. 10% of the filler is also supposed to be preembargo cuban tobacco which is legit as the eioras are one of the only families with any left. They are down to their last bail. Very few of these will be made and it will sport a dark natural/ maduro wrapper.
The other new item from these guys is the rumor of a limited corojo ltd humidor that is supposed to have the same pyramid shape as the box. Not sure what cigars will come in them or if they will be special edition but I am going to fight tooth and nail for the first one off the line.
