time warp - how they did it?

smrt uses this poster to promote the using of the easy-link card(cash card). this photo was taken inside an smrt bus. at first glance, there's nothing unusual about it.

but look carefully, can you find something mind-boggling about it?

if you still cannot find something unusual, look into the picture frame behind the gal holding the easy-link card, as pointed by the arrow "LOOK HERE"

let's blow up the picture. CLICK HERE.

you can see that the whole BIG picture was taken inside the bus, and inside the bus where this picture was take, there's another smaller picture(indicated by the arrow in the previous picture) which was identical to the BIG picture, and mind you, inside this smaller picture, there was another smaller picture identical to the BIG picture and it just went on...... if the resolution of the picture is fine enough.....

QUESTION - how could that be possible? how could the smaller picture be identical to the BIG picture? if it's the case, then some present event already existed in the past. possible???

if it's not possible in real life, can it be done with clever arrangement from the photographer?

if it's impossible for the photographer to do any arrangement that would result in this picture, then it must be some cut-and-paste work from the graphic artist, after the picture was taken.

how did he do it???

just mind boggling!
