Mysterious Llama $20 Dollar Note 2004

Hello All!

I've had this dollar since I was a kid. Being a curious child, I would inspect every aspect of all the currency I had. And either it was the childlike imagination, or some kind of misprint, but I saw a clear llama's front half in the hidden Jackson face.

I took the bill to a local coin shop, but they couldnt tell me anything about it. Only that it wasnt counterfit.

So I'm wondering if I'm just 'seeing an image in the clouds', or if there was some sort of error that happend to cause an image show up.

The images are a little hard to see if you arent in person, so you might not be able to see it. But the llama is facing to the right, with its head just to the right of Jacksons hairline, right before the printed tree. It's neck and torso go down past the right side of Jacksons eye. You can even sometimes see a collar around the lammas neck.

Everyone I've shown this to in person eventually see it. But that may just be me pushing my imagination onto them. I found that once you see it, you can't unsee it. And it becomes a more clear image if you move it a little futher away.

So below I have posted a picture of the front of the bill, and then 2 of the back with the face shinging through.

If no one has an answer to what this is, I would love it if someone else has a $20 bill of same year, federal reserve, and printing location, to see if their bill also has the image, or if the one I have is unique.

Thank you for all the assistant!
