Interestingly the illustrative image says "not valid for travel" - but is the image just the payment receipt and not the ticket?
It will depend on the
TOC▸ , so in the Blackfriar's case that is the ticket. I'd guess
GWR▸ would have a similar format ticket to Blackfriars as they're still using STAR, but
SWR» for example don't have that as a retail sundry and it needs to be done as a manual fare so would look more like a normal ticket.
