This image is for irritation. It's one of the first icons I made myself (for welcomerain, who didn't seem to actually want it). It seems to quite successfully convey a teeth-gritting irritation, which I didn't plan that it would. These are dentures- they are from a National Geographic article on Lichtenstein, from the late 70s (did you know that the #1 product of Lichtenstein is dental hardware? Well, you do, now).
Nutria Alley (which used to be in New York, and is smack-dab-in-the-middle of this graphic) no longer exists. This one is meant to signify digging things up that have fallen off the map; it seems that the icon generally gets used for things off-the-beaten-path which I know, which is another sense it works well for.
It pleases me to no end to have a cute widdwe vampiwe bat to use for posts where I feel especially cosy, at home, &c. If you dig through my memories you can find out a bit more about this little beastie's story- it's actually quite an impressive tale.
