Kralik Bambus/Iris

Bambus is a great signature decor from Wilhelm Kralik (Cir 1925-35). What is rarer than you might imagine is when one decor mixes with another; In this case Iris decor. Iris was the first decor to be found with a sticker; second was Bambus but I think many more stickers are out there to discover.

Question:If you find an Iris finish on a Bambus Decor what sticker would it have been produced with?

I have looked at Iris stickers and they mostly appear on millifiore cane pieces (although other decors with flash iridescence do show up). I have always considered Iris to be a "finish" not a decor but I'm sure the company had different ideas about how to market their lines. The reason I categorize Iris as a finish or treatment is that the finish can appear on many decors and can even be combined with other finishes; overshot for example.

after a 10 year search these are the only examples I have (excluding Marquetry pieces)... so any pictures of "Bambus-Iris" would be very helpful for my files

P.s. the last pic shows the finish the best but it is strong in all the pieces
