How to delete an event logo?

[Guus der Kinderen]

Following the guidelines at https://www.eventbrite.com/developer/v3/reference/uploads/ and using the resulting ID as a value for event.logo_id in POST /events/ allows you to add an event logo to a new event. 

Also, POST /events/:id/ with an event.logo_id allows you to update a pre-existing event with a new logo. So far, so good.

How does one remove a logo from an event?

So far, I've tried:

POST /events/:id/ with event.logo_id = null 

This does not appear to have any effect.

POST /events/:id/ with event.logo = null

This results in an error.

POST /events/:id/ with event.logo_id = 0 

Also results in an error.
