Marcos Waldemar & Invisible Compass – The Erdnase Project

Introducing The Erdnase Project – Marcos Waldemar

A Monographic Study on the Erdnase Change

The Erdnase Change is one of the most iconic, studied, and debated techniques in card magic.

It was first published in English in 1897 by August Roterberg in New Era Card Tricks, under the name “Excelsior Change”, attributed to Adrian Plate.

Years later, it would be popularized by S. W. Erdnase in the classic The Expert at the Card Table.

Since then, it has been reinterpreted by generations of magicians… When executed well, it may be the most powerful and practical color change there is.

When executed poorly… it’s an abomination.
