SMALL PRESS EXPO’s galaxy of special guests just keeps glowing brighter.

SPX announced Monday that the New Yorker art editor Françoise Mouly and the Eisner-nominated cartoonist Adrian Tomine have been added to the lineup for September’s event.

The Paris-born Mouly and her husband, “Maus” creator Art Spiegelman, launched the great RAW series in the ‘80s, which offered a showcase for such talents as Chris Ware — who was announced earlier as a guest at this fall’s SPX. She has helped foster and cultivate at least two generations of top indie cartoonists — including Tomine; started the imprint Toon Books; and has art-directed scores of memorable New Yorker covers over nearly two decades.

The Sacramento-born Tomine, who possesses a beautifully precise style, broke through in the ’90s with his excellent Optic Nerve comic series. His engrossing graphic novels include “Shortcomings,” and he’s a contributor to the New Yorker.

This year’s scheduled guests also include Dan Clowes (“Ghost World,” “Wilson”) and Gilbert and Jamie Hernandez.

The Small Press Expo will be Sept. 15-16 in North Bethesda.
