ok so no one wants all those world mix :-( no problem. was it not a good offer?

today I finally have some time to relax and thought I'd show this block. I have quite a few courtesy of the friend I met here for dinner a few weeks ago, a stamp dealer I think I told you about. I have read that blocks are very collectable and I have to say the condition of these is pretty good. Anyone have any idea about value or interest of such material.

Best wishes and have a great weekend .... Michael
