What are some props i can buy from a store that symbolizes Christopher Columbus? Ex. (Sailers hat, wardrobe, some other than clothing b/c that's easy) I need atleast 7

Probably use something like a small ship for instance.

You can also buy like a map, cross for his spread of catholicism, an telescope for sailers, compass, an earth globe to represent his disapproval on flat earth and a the flag of Spain for they were the ones to sponsor Columbus's journeys
