While coming home from work today, I saw a car with the following decal in its rear window; it looked like a six pointed “Star of David” but the inverted triangle was replaced by a heart shaped triangle. Is there any name and/or meaning behind this sign?
Thx in advance
This?
It’s a “heartagram”, symbol of the band HIM.
Whew, you got here just in time. Before anyone else! 
If it was an actual star of david rather than a pentagram, Leonard Cohen used a similar image on his collection of poetry, ‘Book of Mercy’.
Has the band “Him” ever toured with the “Who?”
