The first photochromotype
In a supplement to the Fotografický věstník (Photographical Bulletin) was published the first photochromotype - “three-colored zincographical plate” - from the Husník-Häusler works, valued abroad. In the same period was published a photochromotype from the same firm in the magazine Z říše vědy a práce (From the kingdom of science and work) (No. 1).
