Melissa Rivers marked her first Halloween without her mom Joan by posting on social media an adorable old photo of them together.

The 2004 snapshot shows the famously close mother and daughter -- both wearing dark sunglasses and black clothing -- at a children's charity event. Joan can be seen clowning around in cat ears, while Melissa rocked a Snoopy shirt.

The elder Rivers died in late August from complications from surgery. She was 81.
