Since you'll be doing this in the summer, just follow the sun in relation to your watch. Whatever timezone you want to be in, make that your noon sun and start hiking.
I mean, that's when you'd *want* to be trying to tackle Antarctica, but I didn't know that was a given. That's your best shot at it of course, if only for the weather and visibility factors.
Needs "The Other South" and "The Other Other South".

Wherever you start on the continent, heading South will take you to the pole.
Now if you want only one North and multiple Souths on an image, you'd need to show the North Pole. And that may be navigating on ice or open water.
Then again - if we're talking magnetic compasses, this wouldn't be accurate because it's not presently located on the continent of Antarctica, it's actually over water. Is that what you're getting at? All ways are truly north from the geographic South pole, but a compass wouldn't reliably produce that result from either pole. Right now you could conceivably start at the magnetic south pole, end up traveling geographically south before then beginning true northerly movement.
Which is all to say that, unless you have a GPS device, you're probably going to die, at either pole. Visibility can be shit with high winds and blowing snow, obviously the brutal cold is a major factor, and you'd have to be an old-school navigator with knowledge of star, sun, and moon positions and relative motions.
I will not be signing up for this.
