This animation cel from the Filmation Aquaman cartoon series was sent to me (among other things) by our newest F.O.A.M. member, Daria.
Daria is a self-professed obsessive fan of Aqualad/Tempest, and she even has a site devoted to all things Garth, called Tempest's Purple Reign. (A whole site devoted to one character? That's crazy!)
She also sent me a pic of her personal Aqua-Shrine, which naturally features Aqualad prominently:
Daria says this is but one of the Aqua-displays in her home ("He and Aqualad have taken over my bedroom and bathroom"), and she sent me other stuff which will show up here eventually.
Thanks Daria, and welcome to F.O.A.M.!
