Cork bluebill decoys (1958) male and female

Hello,

Here's 2 cork oversize bluebill decoys. I know that they have been bought in 1958 a big New York store. Unfortunately, I don't know anything else about it. I would be interested in getting more information about its history and value.

Note that I didn't see any marking on it.

If you know anything, please let me know.

Best regards,

Mathieu
