Here's an interesting line of stuff featuring the Caped Crusader and his foes!
Now, this first one may actually be an older one than the rest of these... this is a Batman bookend set, or at least one of them.
The rest of these are nightlights, and I'm guessing they were made in the 1970s, like the Penguin above!
Here's the Joker!
I'm 99% certain there was a Catwoman one, too... and was 98% certain I had a photo of it, but I can't find it in my files at all right now!
