What rational explanation could there be for having a lowercase and uppercase L in the same word?
It couldn't have been a space issue - there's room for the capital L in the middle. Was the person in a hurry? Or just CIUELESS?
Yes, it looks like the copy editor was in a hurry. But he probably didn't forget to capitalize this first L in AVAlABLE. Rather, it looks like he left the entire L out of AVAILABLE. A visually stunning example, nonetheless!
