Large Antique Sheet Music Hand Painted Calligraphy Vellum 2 Sided L@@K!!

Description

I found this at a sale in a rather unassuming frame (not included). It appears to be old and I've seen other comparable items that claim they are from the 16th-17th century. I have no way of knowing how old this is.
Measures 19.5" x 16"  Examine photos carefully! I am happy to answer any questions or send more photos! Ask Questions!! See Photos!!
Disclaimer Regarding Old, Vintage and Antique/s Items I sell:

Vintage items are imperfect due to age and may contain different kinds of flaws and I may not describe everything of concern for each individual.  I am fully transparent about the condition so look carefully at the photos/description  and if you would like confirmation or information about things you see (or don’t see), please send a message and I will check it for you before you make a purchase. Otherwise, please kindly take all items as vintage / antiques that have sometimes acquired imperfections over time which make them all the more wonderful  and collectible.  I always do my best to provide photos that honestly reflect the character of the piece.
