NIB Vintage Must de Cartier Wallet

i was cleaning out my mom's closet and found this vintage must de cartier bifold card holder. i don't know how old this is, but it is still brand new in its original box. i've seen a similar one being sold still by cartier which they call the international wallet with gussets, whose retail price is $450.

this is made of smooth burgundy leather, and has the double c logo on the front.

please email me if you have any other questions.
