On 12/17/71 I talked to Mr. [REDACTED]
[REDACTED] Washington Bankers Association, and
requested him to send a bulletin to all of their members,
requesting that they alert their employees to any large
deposits in the amount of $20 denominations, any strange
use of safe deposit boxes, large payments on notes or
mortgages where bills of $20 denomination in substantial
numbers are used, and at the same time asked that they
check these bills against the list of hijacked bills.
