Narrative:
Descending on the ltown six RNAV arrival into mem we descended below FL240 approximately ten miles prior to axxel. I realized this at 23;500 then quickly corrected and climbed back to FL240. Nothing was said by ATC.this could have been prevented by paying closer attention to the notes on the arrival as well as the commercial chart enlarging the arrival to a fold out page and having the restrictions labeled next to the fix instead of a note located elsewhere on the page. The fact that the arrival has been split into two sections on the small page indicates that there is not enough room on the standard page for this arrival.
