I don't know around you, but at least in my environment the salamander iconography has caught on... let me explain.
There are a LOT of people who like the "lizard" decorative motif (me amongst them), and additionally I've found it's quite usual to give something with a "lizard" in it as a present. My second ex bought me a t-shirt with a lizard quite similar to the ones in the knight, I also have a lizard made out of beads hanging from a thread braid in my hair (made by a friend of mine, who taught me how to make them and we exchanged lizards) I made a lizard pendant out of leather and electronic resistors (pic here:

I can't recall any more instances off the top of my head, but somehow, little lizards have stuck as contemporary folk iconography, and with quite a presence to boot... and I think that's because they're not just lizards, they're *salamanders*. It may sound far fetched, but I think that people somehow know or feel that salamanders are a symbol of something, and decorate themselves with them as a way to empower themselves - decorating yourself is always a gesture of self-empowerment.
Funny enough since most of people hasn't ever heard of the symbolism of salamanders, even I liked them way before noticing them in the tarot cards, when I realized they were there I went "WTF these cards are chock full of lizard-thingies!"
Wouldn't this mean that a lot of people are unconsciously tapping "salamander power" salamander symbology? I have yet to find someone who DOESN'T like the "lizard" decorative motif!
