Vintage M&T Manufacturers & Traders National Bank (M&T) Leather Checkbook Cover Bill Fold Holder Wallet. Measures 6" x 3.5".
Vintage and in worn condition.
M&T Bank traces its origins to the founding of Manufacturers and Traders Bank in Buffalo, New York. Based on name changes in 1969 I'd guess this piece is from the 60's.
The inside has a very interesting article snippets about old shipping, international currencies. Not sure where that came from.
