From the original "Voyage to the Bottom of the Sea" movie made
in 1961 produced by Irwin Allen. These mini depth charge mines
were used in the making of the film. The props are made of
"Styrofoam Balls and toothpicks".
They were all hand painted by Hollywood artist. "Recently, I
have seen several of these sell on eBay for $200.00 a piece,
and in poor condition!"
