addressing mail to the usa from overseas

[DAVID THOMPSON]

i have received several pieces of mail of late ..
from other parts of the world
that i was surprised they arrived

below i posted what most postmen are used to seeing here

a zero is a bit oblong
a zero in a radio call sign has a slash
but may make a high speed mail sorter mess up in an address
the letter o (oh) is round
a one is best if its just a straight line
and a seven has no cross mark 90% of Americans do not cross a seven (7)
below is a picture sample of how i write them

if its important stuff its a real pain if it gets lost
