Found this display board at Brentwood United Methodist Church Youth to be really impacting. It is two large black plywood boards put together with plaques in black which have a photo and a write up of teenagers and children who were sold into the sex slave trades. The plaques are on hinges and open up to tell more of their story when you can take off the locks which hold the teens and children ‘locked’ in an injustice.
This can be an ongoing project display where you put a few peoples stories and they are locked until the youth are able to raise funds to help ‘free’ someone. Then their story is unlocked. Then go to work on the next young person. It can be for a sermon/talk series or retreat setting where you want to have some creative illustrations for this injustice.
