The goal was to raise enough money to help strikers get back on their feet.
"We are here to support the community, and there are a lot of folks who are in need of money. So we're here to support them," said Lauren Shand of Propstore. "They can work on consigning items with us, we can help them with some cash advances if they can't pay rent. So, we're trying to help the community."
The event marked the first time the prop vendors had been open to the public.
