Yep, alas poor Ivy is not with us anymore. So many of my fav characters have died in the DCU and Ivy was one of the top. It's hard to explain that story but I think probably got this from one of Grimbor's pages. Also before she got the green skin tone (still wondering what caused that) and ended up parading around alot barefoot at times.
Remember seeing a scan from a comic once where Batman somehow knocked Ivy out (green tone one) and she was barefoot and he was in the middle of tieing her up and Robin started asking something and then just let it go. ( I think it was why he always does what he was doing to her or something.) It was funny but man wish it was a closer front view shot done of this.
Thoughf or another barefoot Ivy try and find the Joker/Mask books she's barefoot in that (and in the normal flesh color for those that picky.) Hint on the story, the Joker gets the Mask of the Mask and puts it on. Simple enough you know how crazy the Mask was, think how scary this is gonna be.
