I'm still mildy behind on older news on here. This one in particular is coming in exactly one year later.
As part of breast cancer awareness month last October, Marvel partnered with the Susan G. Koman Foundation. Many covers were given a pink makeover, and often had a strong emphasis on the female characters attached to their respective title's family.
Wolverine in particular for issue #315 had a special X-23 focused cover.
Here's that cover from last year.
Special thanks to Wolfy Cosplay for this heads up on the missed news!
