Is this map original?

[u/Sure-Background1116]

I bought this map today at a map shop in Paris for 80 euros, and I was wondering if you could help me verify its authenticity. According to the shop where I purchased it, it is a 17th-century map.

It is by Nicholas Sanson circa 1660ish, printed in Paris. 80 Euros is a good price for it.
