Wonderful reprodutcion of very rare bonds of the Third Reich!
500RM, 10-years bond issued in 1938. With 4.5% annual interest paid twice a year until 1948. As you may guess, the payments for the last 4 years didn't really materialize.
The set includes:
main bond certificate
2 sheets of interest payment coupons (20 in total, 10 per page) 
 
As you can see the bonds aren't always a no-risk investment...
