Many years ago I started collecting tickets from each station on the Underground. I managed to buy one from each station (even managed Blake Hall!) but it's occured to me that there have been a few additions to the network since then (JLE, Wood Lane), so I need to add these to my collection. My question is, do the single journey tickets issued nowadays have the name of the issuing station printed on the front or are they just a generic 'zone number' thingy?
