Was it already with the same text/emoji combo?
Cause that particular tears of joy emoji only became standardized in Unicode 6.0, 2010. It was presumably around a bit before that but nobody except the Japanese really did a lot of emoji stuff much before that (iirc Google and Apple only started adding the first emoji to their keyboards 2007-08).
Either way would find it very interesting if somebody was already using the emoji way before that, or the text area of the picture went through multiple iterations.
