Earlier this week we spotlighted Jon Morris' call for comics fans who'll file into theaters this weekend to watch Marvel's The Avengers to match their ticket price with a donation to The Hero Initiative as a "thank you" to the people who created those characters in the first place.

It's a fantastic suggestion, of course, which led me to think of a few other options for showing some financial appreciation. Think of it as the comics version of trickle-down economics, or something:

A Buck For Jack: Launched last year by cartoonist Nat Gertler, this campaign encourages fans to donate $1 for each of the movies they’ve watched that features characters co-created by Jack Kirby. “If we could get just 1% of the people who see a Kirby-inspired movie to throw in that buck -- and yes, 1%, as small as that sounds, would be a huge and unlikely success, I admit -- that would be hundreds of thousands of dollars per movie going to the Kirby legacy,” he writes. The money collected through the Buck For Jack website goes to the Jack Kirby Museum & Research Center, although Gertler notes that, “if I ever find a way to give it to the Jack Kirby heirs instead, I will start directing the money there.”

The Jack Kirby Museum & Research Center: If you'd prefer, you can donate directly to the Jack Kirby Museum. Established in 2005, it still only exists online, but the trustees are working to change that. The organization, whose mission is “to promote and encourage the study, understanding, preservation and appreciation of the work of Jack Kirby,” has established a Brick & Mortar Fund in hopes of finding a temporary "pop-up" location for the museum in New York City, preferably near the Lower East Side neighborhood where Kirby grew up, with an eye toward of a permanent home.

The Comic Book Legal Defense Fund: Familiar to creators, retailers and fans alike, the Comic Book Legal Defense Fund is dedicated to the protection of First Amendment rights of the comics art form and community. The CBLDF provides legal referrals, advice and representation, and frequently joins in opposition against legislation that poses a threat to free speech.
