Thanks for all the responses!
I found this card in the parking lot of a big store on a busy day and it was already bent in half, possibly the remains of the original owner's battle with the unknown wand bearers, who knows.
But as for me, now that I can associate it with a tarot card I know, 7 of wands in the good old Rider-Waite deck, I think I can guess what this card is telling me. It was just starting to snow when I found the card, and although I love snow and winter, December is the time of year I often hole up at home and shrink from the world. Just when there are things to do and obligations to meet. So I think this card is reminding me to be brave and overcome my December anxieties, take charge of my life. Let me not be the bent-face-down-in-the-snow version of this chance encounter. I'll be the stand-up-and-face-the-season version instead (I'll try!)
