Do stamps on Eiffel expansion postcards (a red and a blue stamp) score points for both players?

Question

Accepted Answer

The stamps mark who scores rather than adding points. A red stamp means the opponent also scores from that card, as with the Obelisk and the Eiffel Tower. The stamp itself adds no point value.
