Italy - Two pre-philatelic (unfranked) items from 1611

Two pre-stamp (unfranked) covers from 1611 addressed to Vincenzo da Filicaja, a nobleman from a very important and powerful family of that era in Florence and Tuscany. Probably an ancestor—perhaps the grandfather of the famed poet Vincenzo da Filicaja, who lived from 1642 to 1707—so these missives are not addressed to him. The letters discuss private family business of a commercial nature, involving purchases, sales, etc. One is in excellent condition, the other yellowed with time. Considering they are over 400 years old, they may show defects such as stains or tears. Anyway, both readable!!!
