Antique Hooks

Yesterday, another class teacher at work gave me an amazing surprise: a bunch of antique crochet hooks. She said they'd belonged to her grandmother before they came to her.

I think the brown one on the left might be a slip-stitch crochet hook. The metal ones in the middle are all Bates or Boye hooks. The three plastic ones on the right either don't have any writing or it has rubbed off, so I'm not sure what brand or hook size they are. That won't stop me, though. :-) Cool, huh?
