This is a special vintage glassbird from 1986 designed by Oiva Toikka for KOP bank (Kansallis Osake Pankki). You find it on page 125 in the book "Birds by Toikka".
It seems to be some confusion in the presentation of the KOP birds in that book, as there is no picture or adequate description of the small KOP bird. Instead, under the heading Small Bird for KOP a big KOP bird is described. The small KOP bird is bluish silver lustered and about 105-110 x 70-75mm.
On the last picture you see this middle sized KOP bird posing together with the small KOP bird.
Size: 180mm x 120mm Signature: Kansallis-Osake Pankki Oiva Toikka Nuutajärvi Notsjö Condition: Very good-excellent
