Here is a lidded pot from a set in amber glass, but alternative panels are decorated with an enamelled ‘faux-tortoiseshell’ design.

Interestingly, decorative panels in the same style have been seen on another trinket set pattern discussed at
http://www.glassmessages.com/index.php/topic,51881.0.htmlwhere a possible attribution of Stolzle / Hermanova Hut was also suggested but without any firm catalogue proof. Well, the fact that we now have a lidded pot that is almost certainly by Stolzle / Hermanova Hut, with an enamelled decorative design that is, to my mind, identical, with pieces from both sets marked as Czechoslovakian, must surely strengthen that putative attribution beyond reasonable doubt.
