This card is rather exciting, because it shows that bicycling has risen to the popularity that dedicated shops were set up.
And, though our younger readers may not believe it, it was very common once to use an old bicycle above a cycle shop as advertising, often brightly painted with a board for extra advertising. In fact this card awarded twenty points for "any old or modern cycle, tricycle, or motorcycle - real ones, models, or painted - used as a shop sign".
This shop is a bit of a play on words, "Pedlar" meaning one who pedals a bike, as well as a dealer of goods. Though a swift internet search proved that "Pedlar" is often used as part of bike shop names to this day.
According to the Guinness Book of Records the oldest bicycle shop in existence is Pearson Cycles in Sutton, London - it started in 1860, but as a wheelwright, making wheels for horse-drawn carts, for at one time Sutton was a rural place. It obviously then saw a need for bicycle wheels, or perhaps someone broke a wheel outside their premises and they made the link. And, quite wonderfully, it is still a bike shop at the time of my typing.
However it took until 1926 for there to be a British bicycle manufacturer - that was Pashley, of Stratford-upon-Avon.
We have a main page for Priory Tea - I Spy with some background info on the company, and a listing of all the sets, and, one day you will be able to see a specimen card from every set by linking out from there. Not yet though.
This set is described in our original British Trade Index part two as :
SERIES 9 "I SPY CYCLES AND MOTORCYCLES". Sm. Nd. (50) ... PTT-9
It also marks a big change in the series as it was the first set of fifty cards, those prior were only of twenty-four cards. There is a theory that says they did originally plan it as two series, one of cycles and one of motorcycles, but then decided to join the two together.
