These pumpkin / jack 'o lantern fridge magnets are from a company called The Witches of Pendle, who are based in Pendle in Lancashire, UK. The company mainly specialises in witch-related items - specifically those relating to The Pendle Witch Trials in 1612 - but they also carry other merchandise as well.
For some reason, the above pumpkin reminds me of Attack of the Killer Tomatoes whenever I see him. He's cute nevertheless!
The other magnet (pictured above) seems to be some kind of pumpkin-magician-elf type guy. Quite charming really! I don't know if these two are sold anymore, but The Witches of Pendle do still make lots of other spooky things.
