If I tweak things enough, I can make a connection with:

The constellation Cassiopea

The constellation of Gemini

The Washington Monument

Carnegie Hall

A map of selected areas of the lunar surface

I could probably map it onto one of the faces at Mount Rushmore, too.

The fact that you can take one view of one artifact and prove that it's a well-designed piece that follows the known mathematics of aesthetic principles simply means that the craftsmen understood good design. But it doesn't say anything about the artist's intent.

To understand the artist's intent, you have to see a lot of examples of the artist's work. And frankly, why do something so inaccurate (the drawing is of only one view) and elaborate when you could just design a very nice pyramid for the princess?

It wasn't like they had to keep this secret, y'know. Millions of people worked on pyramids. If someone had wanted to gift her with a pyramid symbol, there was no reason to disguise it.
