Absolutely new acquisitions for your collection! The ballerina is my favorite by far, such a pretty design. The art work on the Maria-Theresia stamps is great as well, I see why you got all of them in uncancelled condition. I like the triangle stamps too, but they are odd to fit into a collection album, when I collected stamps I never had too many of those.

The Hitler stamps are interesting for historical value I agree, but an individual that wasn't the best human being who ever lived. Along with Stalin and Mao, the trio killed an more people than all the tyrants in history who proceeded them. That's why those pieces of history are important to keep around as reminders of the horrors of war.

The Franz Joseph set is nice too. How many stamps came in the collection in total for you to collect? They must be much more uncommon to carry that price tag!
