The crowns of the Zodiac

Of course, it's not the real crown. The real one is in the vault for imperial relics in Vienna.
Frederick III commissioned his own tomb 30 years before his death.

"Decade Project
Frederick himself had already commissioned his tomb in 1463, thirty years before his death. Nevertheless, it took another twenty years before it was completed: in the meantime, the deceased emperor had to wait in the Ducal Crypt of the Cathedral before he could finally move into his final resting place in 1513. Frederick's son Maximilian I had pushed the project forward and documented this in detail.

This is also how the crowns of the predecessors and successors should be viewed. For example, Maximilian I had a different crown than his father. So also the archduke ( brother ) had his own crown, although not an imperial one.
To understand everything correctly, one should take a look at the history of the Habsburgs from 1250 - 1450.

With the empresses, they were depicted with imperial crowns as well as with their own.

The crown of Frederick is common. From Bern Zurich to Vienna, and Hungary and from Prague to Italy
