The 2-part box is very good - no broken corners.
There are 60 cards to the game and it is complete. There are 5 colored suits with 12 numbered cards each.
The original 4-page instruction leaflet is present along with a 6 page primer for the game.
Also included is an ad sheet for other Parker games.
Board Game Geek describes the game and provides an interesting snippet of history:
PLAZA is played with a five-suited pack of 60 cards, the suits being distinguished from each other by color (each color also has a little picture of an animal to help distinguish suits), the cards run from one to twelve in each color. A game turn consists of Draw, Play, Discard. Similar colored cards are placed in a row and similar numbered cards are placed in a column, eventually forming a card grid. The winner is the first player to run out of cards. This game was original enough at the time to get a US Patent (#952939)
