1930 Book Bank

Picked this little jewel up at a yard sale today. According to the patent no. it is from 1930. The bank is metal covered with a cardboard embossed title board and binder. The corers re sealed with brass clips. Just liked on sight.The back panel has a tear in it but for being over 80 years old it's in good condition. The cover is titled Investors syndicate &Guarantee Company of New York.
