QUIZ: Can you name the county from their jersey sponsors?
If you get even 30 out of 33, we'll bow down to you.
We all love a jersey but just how well do you know those jerseys?
Across every one of the 33 teams that compete in the All-Ireland Senior Football Championship - and we haven't left out Kilkenny either - there's a lovely big logo planted in front of all their shirts.
We've had a look at every single 2017 inter-county jersey and all we're asking you to do is match the logo from the 2016 sponsors with the county.
*Disclaimer: These are official company logos - some of them may have changed colour or shape for their respective jerseys.
