GE’s release said:

Perhaps there should be a bumper sticker: “If you love doing stuff at night without a kerosene lantern, thank Edison.” Okay, it doesn’t roll trippingly off the tongue. Still, today is the anniversary of Thomas Edison’s 13-and-a-half-hour test of the carbon filament lightbulb that made electric light a practical reality for the world. As we’ve discussed before, Edison was one of many inventors of the lightbulb, but his designs proved to be transformative for the technology. Maki Naro marked the occasion with a short comic (replete with Alexander Graham Bell, who’s hoppin’ mad).

Too commercial for classroom use?  Not with proper attribution, I think.
