I think we're talking "fantasy iconic" here. I've never seen anyone play a Keebler elf. (Anyone who did would be treated as if they're playing a kender, gnome or other annoying comical race.)
We weren't, but we can. Specifically, I was responding to an argument from pop culture that said the most recognizable gnomes are Travelocity's roaming gnome, david the gnome, etc. Using that same argument, elves bake cookies and make toys, while gnomes travel the world and work nature magic.
If we're talking "fantasy iconic," the most iconic gnomes I know of outside of D&D are generally treated as earth-elemental type creatures similar to dwarves, but smaller and closer to primal "earth-magic" than the dwarves are. If a dwarf works metal and lives in a clan, the gnome slides through the earth like a fish and conjures gems and stones from nothing, while being born out of "gnome eggs" that resemble geodes.
The most iconic elves I know of outside of D&D would be the super-powered, near-divine, "everything works out for us and we always look stylish" uber-elf of Tolkein and his related rip-offs.
Neither would be very valid as a player race in D&D, IMO.
