Friends, let's clarify something here before we get too excited. Yes, it's true that Bulgarian Order of labor Glory was setup in such way that higher classes were given to folks who were previosly awarded lower classes. However, I am not aware of any special Cavalier designation like one in Soviet Union, where the recepients of all three clases of Labor Glory were given Cavalier Booklet. In many years collecting Bulgarian awards I've never seen Bulgarian Cavalier documents. I also never read anythig about existence of such documents. Best regards, William
