We found this in the New York Post and here is an excerpt from the newspaper describing the photos.

'The story of Eddie's [the hamster] wild ride dates back to 1996, when the District Attorney's office was preparing for the trial of crazed subway bomber Edward Leary. Prosecutors needed a model of a subway train to show jurors just where Leary detonated his explosives.

Architectural engineer Marie Venticinque was enlisted to construct the tiny train car replica.

 The model did its job - Leary is a serving 94-year sentence for assault and attempted murder - and ever since has sat on a shelf in the DA's engineering unit.'

Enter Victoria Balenger who is a photographer with DA's office. She saw the train and recognized that it was 'perfectly hamster-sized' and brought the very tame hamster into work yesterday for the photo shoot.

PowderRoomGraffiti says well done Victoria.
