This is the next Economic Policy enhancing Adjacency bonuses, this time for the Theater Square. However, getting Adjacency bonuses for this district is most problematic of all districts - only Wonders provide a Standard bonus, while other nearby districts provide the usual Minor bonus. So, your Theater Squares will have little or no bonuses, unless you manage to surround them with other districts, and/or build lots of Wonders. Alternatively; Japan and Greece can make wonderful use of this card due to their bonuses to Theater Square/Acropolis adjacency that gives them consistently high yields!
