speech bubbles

Slipping this new one under the wire... The small bubbles in the central current come from The Great Women Cartoonists by Trina Robbins. They're in chronological order from 1902 in lower left to 2001 at upper right. The rest of the bubbles are just... from everywhere.

For the comix geeks among you (and more power to you!), there is one item that's technically not a speech bubble, but text on a flash panel.
