Different logo dependant on source visitor

Hi,

I have the next question:
We have 3 websites. Site A & B are the normal websites. Site C is a webshop to where A & B link to via a button. Imagine a visitor is on site A and clicks on a button to go to site C, is it possible to show on site C the logo of site A. And when he comes from site B to C, to show the logo of site B?

I hope it’s a bit clear. I know it’s a weird and maybe an impossible question, but would be great if it’s possible!
