To date, we have two entries of high calibre.
How to make change (to get coins from a banknote) in Italy?How to make change (to get coins from a banknote) in Italy?
This entry nails it with a photo of the Comestero coin validator/dispenser as found all over Italy (possibly a monopoly?). The OP will be able to immediately recognize what they are looking for.
Berlin to Göttingen by train - which Berlin station to use?Berlin to Göttingen by train - which Berlin station to use?
This entry nails it with an image of the ICE in the Berlin Hbf. It's an absolute augmentation to the OP's question, and the OP will be able to recognize Track G when they arrive in the station.
I see both of these entries as exemplary (and well above expectations). The bar has been raised!
Neutral observers are invited to check these out. Vote both, vote one, or abstain.

My own attempt is here British citizen, why does my South-African wife need a visa to visit me in the UK?British citizen, why does my South-African wife need a visa to visit me in the UK?
This image is thematically on target because it demonstrates the sort of performance issues that led to South Africa's exclusion from trusted status (in this case overstay and illegal working). But it doesn't match the calibre of the previous two examples because there's nothing definitive to indicate that the persons getting busted are South Africans. If they were identified as South African nationals, it would be perfect. The image itself comes from the Home Office library and they fed it to Twitter, from there nearly every major news outlet ran it along with a story.
