This book from the 1700s

So this is my favourite antique thing I have. My grandfather bought it at a garage sale in Paris, during the 1960s. He bought it for like 5 €, along with other religious books from the 1800s. It’s crazy to me that stuff like this even exists anymore and the handwritten messages/notes make it even more special. Also so find it crazy that my grandma was like: „ah yes, I know, it’s pretty old. You can have it if you want“ … like god damn thanks!! I was freaking out and she kept her cool like that lol. Anyways, I hope you guys like it as much as I do
