Any facts on dangers of old toys containing chemicals?

Even if some of it does get out, the potential exposure to bromine from handling old plastics is trivial compared to, say, drinking orange soda or other product containing brominated vegetable oil. Here’s a case of bromine poisoning from drinking a gallon a day of BVO-containing soda:

The tool marks in the middle on the right are missing on the after part, as well as the missing chunks of plastic on the middle left.

I think that the different flash angles highlight the piece to create that effect. Look how the shadows created by the ‘posts’ shift.

Neat process, and one I was not aware of.

Contrast is different, but if you zoom in and look really careful, they’re there.

While we’re on the subject of Lego, anyone have a good method for cleaning a large bulk of Lego easily? I’m tempted to pick up a lot of used bricks and I’d like to clean them up before they go into the collection.
