easy: 'Phoebe' @ simonscans
at simonscans they have a model index, so you just look at any pic, note the four digit number in the corner (usually lower left) that number's called a 'year'. So you just browse throuth that particular 'year' over at their site to look whether you can find the chick you want. ;)
In this case, it's here:
