This is not the usual (Canadian?) maple. But I believe it's either a Japanese decorative maple or something quite similar. Or it's possibly an elder leaf. :-) I cleaned it a bit in Photoshop, and if you need a 150 dpi version, I have it. When I get home tonight, I'll scan some more leaves I picked up this morning. Not certain about what's the name for the trees I picked them off from, only for a willow leaf. I'll also pick an oak leaf and some others.
