Bootham Bar is the one of the famous gateways through the city walls of York. There has been a gate of one kind or another here since 71 AD when the city was founded by the Romans. At that time, the city was known as Eboracum. When the Angles took over in 451 AD, the city became known as Eoforwic, which has a certain ring to it if you can pronounce it. It didn't become known as York until the 13th century.
York started out with horse-drawn carriages or buses as public transportation (i.e. no rails). They also used steam-powered trams briefly before changing over to electric trams in 1909. If you look closely, you can see that this one has two decks, and the barrier on the top one is quite low. Sit down, gentlemen or you may be knocked off the tram when we pass through one of those gates.
As buses gained in popularity over the next few decades, the decision was made to stop running the trams. The last one ran in 1935.
Here's the back of the card, showing that it was printed by E.T.W. Dennis & Sons. I don't encounter their cards very often.
