You mean the Saint pictures on a card with a pray on the back for your walk with Christ or a funeral card( people are sentimental but still a pray)? I think you also mean some cards touched to a relic? yes?
I’m not sure what you’re talking about but I remember a picture of some man (presumable John or Paul) but the image was kinda spooky. Can’t remember what was on the back of it but I remember him saying he kept it wherever he went.
