So do I, and I've had some drafting training.
111lll1111lllllll11111lllll11111llllll111l hmmmmm I was wondering if I hit l instead of 1 on the 1 :-). Can hardly tell the difference on the computer! My monitor is going fuzzy though. Just like my brain. LOL. (Now after previewing when it goes into print, I can really tell the difference between the 1's and the l's!)
The only other comment I can offer at the moment is that whoever has done this shows consistency in their style, dashes, printing, everything.
The person blocked the words that wouldn't fit on one line of the address. Usually I indent or string it somewhere else.
All this is silly, of course, but one little clue could help to solve the case.
