If Marcus thinks not then I'd be inclined to be guided by him... they really don't strike me as being in the style of Hanus and they aren't in either Marcus' book, Sklo Union Art Before Industry, or in Petr Novy's book about the work of Vaclav Hanus, Everyday Art.
The only reference I can find to this item being by Hanus is the spurious one on designhandlung referred to above, can you tell us what/who was the source of your attribution please?
