Some folks
have an idea that these things are scarce,
which they aren't.
Just as a supporting argument you might want to list two or
three places where a person could go and get one of these.
I own 4. I know where at least 6 more are. None presently
for sale however. They were once VERY common in banks in this
area (They were in every Citizen's Bank of Maryland I went in
to in the mid 1980s... probably had 10 per branch in more than
100 branches, two credit unions I belong to used to be littered
with them, the last ones replaced only 4 or 5 years ago). Some
may have been 3As but all were the two tone blue, light on top,
darker on bottom.
