Armored men. I rather wish the tournament knight had come with a detachable shield, making him more useful as an early 16th century man-at-arms, but still it's a good figure.
The halbardier is more of a "tweener" who can bridge the gap between the early 16th Century and later, but the musketeer and mounted figure look like 30 Years War, hence the Matthaus Merian backdrop. The musketeer comes with mold cavities for two heads but he's somewhat oversized relative to the others. The rider cuts a dashing figure. Although so far as I know of the 30 Years War, figures bearing lances are usually depicted in 3/4 armor, he appears to have some conversion possibilites. He could be easily become a standard-bearer, or replace the lance with a musket and you could have a nice dragoon.
Lastly, although it has nothing to do with Meisterzinn, here's a quick shot of what's in the painting queue.
