Topic: Is this bowl part of Mstisov's Harmony range?

[Anne E.B.]

My bowl shown at the bottom is from the Mstisov "Harmony" collection (no.53129) c.1950s and most probably designed by Frantisek Zemek, but is the bowl shown above also part of the same collection?  I think the one with an indent on either side at the top is most probably an ashtray whereas the other is a jardinere.  They are so similar in design and with flat polished bases but differ in colour, (one being blue with green 'streaks' and the other being green with blue 'streaks') and I feel sure they must be related.  Both are roughly the same size too. 
Many thanks for your comments
