"Cities". Proofs of 2 Kuna in imperforate block of four, with  gutter and 6 Kuna in imperforate block of four, both in changed colours: olive green colour shades. The gutter is creased as usual. Se-tenant pairs of different values with gutter are rare, few stamps also show some unrecorded plate flaws.  Few stamps are somewhat creased, one 2 Kuna stamp has a brown stain.
