This sign is at the National Gallery in Canberra. It is about their current exhibition which is well worth seeing.
They had more complex information to convey, but it broke into three parts - hence the bigger writing on the sing. This meant that you did not have to read the whole sign, just the part which related to your circumstances.
They were saving your time and giving you the information you needed, easily. There were several of these panels on the way in, so which ever way you approached the gallery you were likely to see them.
I was interested that none of the signs had social media connections, but perhaps I missed them.
The signage for the exhibition was excellent.
