Count the "Easter Eggs" in the background of Elizabeth Warren's DNC speech last night

Last night, US Senator Elizabeth Warren, a former schoolteacher, gave her 2020 Democratic National Convention speech from an early childhood classroom. Just beside her left shoulder, you can see three wooden alphabet blocks spelling out B L M for Black Lives Matter. And that wasn't the only subtle message in the background.

From ABC News:

Warren's team shared more information about the Easter eggs in a Twitter thread. These included a postal worker jacket that emphasized the efforts to save the USPS, "Joe" spelled out in blue letters on top of the lockers and artwork that reminded people that Election Day is on Nov. 3.
