Anime Ace is a particular favorite of mine for speech bubbles and narrative blocks. Badaboom works well for in-panel sound effects. There are many others, but those two remind me most of my Marvel childhood. (I has Spidey #1 and Hulk #1. They cost a dime at the time, and who the hell knew they'd be worth anything? Same with my Bobby Orr rookie cards -- I traded a bunch of them away for proper Leaf players, and wound up putting the last one in the spokes of my bike the next season.)
