Clarification: Marvel's newsest ratings system

A couple of customers have recently asked me if the "A" on the cover of SPIDER-MAN UNLIMITED stands for "ADULT". The answer: No, of course not! It apparently stands for "ALL AGES"... here's Marvel Comic's official explanation of their relatively new ratings system for their comic books and graphic novels, for your reference:

MARVEL RATING SYSTEM
* ALL AGES
Appropriate for readers of all ages.
* T+
9+ years old Appropriate for most readers, parents are advised they may want to read before or with younger children.
* PARENTAL ADVISORY
15+ years old Similar to T+ Suggested for Teen and Up, but featuring more mature themes and/or more graphic imagery. Recommended for teen and adult readers.
* MAX: EXPLICIT CONTENT
18+ years old Most Mature Readers books will fall under the MAX Comics banner, (created specifically for mature content titles) MAX and Mature-themed titles will continue to be designed to appear distinct from mainline Marvel titles, with the "MAX: Explicit Content" label very prominently displayed on the cover. MAX titles will NOT be sold on the newsstand, and they will NOT be marketed to younger readers.

Marvel ratings serve as general guidelines for readers. In many instances, a PSR title may be appropriate for most age groups. Marvel leaves the final determination of what is appropriate content up to the consumer.

There. Remember parents, YOU know what YOU want your kids to read and not read... use these guidelines when shopping... and ask US, too! We live to serve!
