It can be effective as a conversation-starter, both among professing Christians that do not yet know each other and also in an evangelistic way.
When I was a teenager, I had a lot of these "conversation starters". I had fish signs and crosses and various other things printed on T-shirts and plastered or drawn on my notebooks at school, but they never started any conversations. The only exception was my T-shirt that had "PBPGNFWMY" printed on it. People would ask me why I had half the alphabet on my T-shirt and I'd explain what it meant. Christians thought it was cool, but everyone else thought it was just weird and the conversation never went any further.
