Also, not exactly Indy-related, but although I was greatly interested in their replica of El Corazón from Romancing the Stone at first, I've found that they seem to have taken the jewel's name a little too literally.
Here it is in the film:
Theirs is far too round and far too literally heart-shaped, versus the more angular and pointy stone seen in the film.
There are far better (and likely more expensive) replicas of El Corazón out and about, I just can't find them for actual sale, just pictures:
Until then, though, Toy & Prop Masters' El Corazón (or "green glass jewel," as they call it, suggesting they are unaware of the stone's actual name), despite being inaccurate, seems like it's a decent buy. I E-mailed the owner and it turns out the jewel itself can be purchased from them without the map for only $12 which seems like a steal.
