Speed Force turns five years old tomorrow (hard to believe, huh?), and one of the ways we’re celebrating is with a photo challenge. (See, I told you we had something in store for our Instagram page.)

To participate, follow @SpeedForceOrg on Instagram and post a photo of your favorite Flash item tagged #speedforce5th.

It can be a comic book, a toy, a statue, a costume, a poster, a piece of original art, a DVD, a shirt or towel, a game piece, anything. It can be official or custom-made. It can be something you own, or something you’ve seen.

We’ll post the highlights next Friday. (Please post your own photos only.)

If you aren’t on Instagram, don’t worry — we’ve got something else planned that you can participate in too!

Wow, five years. Big thanks to Devin, Greg, Lia and Ed for joining me on this journey, to everyone who’s guest-posted, to my wife and son for putting up with me spending time on it, and to all of you for coming along with us!

When you get home from “Man of Steel” this weekend, check on Speed Force. We’ve got a lot more in store as we celebrate our fifth anniversary!
