Italy - Over 130 antique pre-stamp letters (unfranked)

Fascinating mixed lot of over 130 items, including envelopes and letters of private/bureaucratic character.
One is from 1617! perfectly legible considering the more than 400 years; I would say truly in good if not excellent condition!
Many are addressed to a nobleman in Senigallia.
4 stamped documents.
I’m selling in a block, as you see it; I don’t have time to catalog etc. Some are better than others, may show yellowing, tears, etc., but overall I’d say they’re in good condition!
Check all the photos to get an idea of what is being offered.
Happy bidding!
