I and J

Its July so I'm going thru my files looking for things with a J theme. You may be aware that the letter J developed from the  I letterform. Here's a comparision of the letterforms to illustrate this. 

Here are some modern fonts clearly influenced by hand writing.

Given how similar I and J are in some fonts and calligraphy styles I hope my choices are show how emphasizing the top bar made it easier to distinguish the two letters?

Do also check my prior post on J letter forms please?
