Vintage MCM Ingrid Chicago Plastic Party Ball Picnic Camping Set Plates/Cups

Retro Ingrid Chicago 1970s Party Ball Picnic/Camping set of plates/cups. Primary colors (red, yellow, orange, green, white and blue), set includes: the two large bowls that are the container, 6 dinner plates, 6 salad plates, and 6 smaller appetizer plates. Also included are 3 cups (orange, red and yellow). Although 3 cups are missing, the set appears to be unused. Really cool addition to a retro camper!
