I have tried before to make out that postmark date
Indication is that it was mailed out of a Texas post office.
Notice at the right hand corner...the 'X's and the line drawn through a word I can't make out either.
'Q265' ...What could that mean?
The 'Dallas' part was written on a label.
But then, 'Irving' was written directly on the package and it looks like the same handwriting.
Of course the parcel was mailed. It has a postmark but oddly no
'postage due' stamped.
After a fashion...the dead letter people will open stuff with no return address to see if they can find any clues.
