Here is a picture of the Rebbe MaHarash's Megillah. As can be seen the Asseret Benei Haman are at the top. However the listing of the names are not STRAIGHT or JUSTIFIED. Rather, they are indented taking the length of a regular writing without stretching any letters. The same goes for the word ASERET, it is not justified with the Ve'ETS. The Rebbe wasn’t a scribe, but his doctor told him he should do detailed work with his hands. So he wrote one Megillah for each of his children. He only wrote three or four megillahs, one of which is in the Library in New York, and the other by Rebbetzin Carlebach. The above pictures are from the Carlebach scroll. It's in remarkable condition for its age (around two hundred years old) with really wonderful handwriting. You might enjoy reading the following article: http://www.collive.com/show_news.rtx?id=20125
