While years ago some O.Toikka birds (like baby crow) has sold in U.S.A and if somebody else like artist himself has make the signature of item, he/she must make own initial too ( I dont know, is it law or something like that). IT mean INKERI TOIKKA, Oiva Toikka´s wife, who has make the signature and so she must make she own initials all that birds witch has sold in U.S.A. All birds witch has sold in Finland or any other countries are without that IT mark. Information what I have get, baby crow has sold in U.S.A aircrafts and airports by AMEX. I hope you understand what I mean, my english is not good. Raakel
