This school year, the students in your life can gear up with officially licensed merchandise from Aerosmith and Kiss.

The veteran bands have both unveiled back-to-school supplies at their respective sites, including backpacks, water bottles and apparel, all emblazoned with the groups' unmistakable logos. Visit Aerosmith's online store and the official Kiss shop to see the complete product lines.

As fans of both bands are aware, there's really no shortage of official merch where either group is concerned — although the members of Kiss definitely started elevating licensing to an art form well before most of their peers had even begun to understand the commercial potential. The groups traveled together in 2003, co-headlining a series of dates officially dubbed the Rocksimus Maximus Tour/World Domination Tour, and parted ways feeling less than complimentary toward one another.

"They’ve got a couple of hits, but they’re more the comic book — you see them in their speckled faces," sniffed Aerosmith singer Steven Tyler in a 2012 interview. "A Kiss lick and a Joe Perry lick — two different worlds. And I, sometimes, depending on the time of day, get offended. I hear that and go, ‘It’s all right, but do they really mean it?’ And, ‘What’s this all about?’ And that’s why I think Aerosmith has been around forever. We really do take ourselves seriously."

"Steven may have been over-enthused and needs a reality check," retorted Kiss co-founder Paul Stanley, adding that from his point of view, the 2003 tour was good for a few unintentional chuckles. "Steven insisted that they close the show. I really [didn't] care because one way or the other you have to come up onstage. [He] was looking down his nose a bit at Kiss. Seeing him come onstage to an underwhelmed audience and [seeing] people walking out [made me smile]."
