We've got some Horst Kaltenbrunner beauties for your bonsai enjoyment.  Horst's  caption for this photo reads: European spruce that shows its naturalness.

Andrea Maier wrote that this Horst Kaltenbrunner tree is a Beautiful sylvestris in a antimayer pot. You'll get no argument from me.

Looks like the same Pinus sylvestris (Scots pine) that's above. Only from other side.

Horst identifies this one only as a pine.

Horst's caption: Pinus Mugo, collected in Austria two years ago in our mountains, removed the topsoil. Now in the training bowl in pure substrate powered by Ibuki! We give him some years, it could be a beautiful tree!
