Joe Louis speed bag clip

[paranday]

It's quite a large bag he's hitting, briefly, about 1:28 in the video,

There is more speed bag footage later in the video,
where it's referred to as the light bag. Great platforms!

Here are some stills frame captures and lighted a bit. There's as much Steel in those wall units as a modern day toyota, probably.

Great stuff Paranday
Not sure where you find this stuff but it sure is fun to watch.
