I recently found a picture that I would like to get some information on. I don't know when it was taken, but the back of it says "instax Fujifilm". I found on the internet that instax was not release until the end of 1998. The picture was falling apart and when I peeled the bottom of the picture, I found a number "K925204603239". Does anyone know what type of information I can get from that number? Thanks for any help...
