This card gave us "electric" for it is a Metropolitan Line electric locomotive. Electric power may be convenient, and allow us to just flick a switch and light our homes, but it is very wasteful of resources. The first thing is that the fossil fuel that we make it from sends various greenhouses gases into the atmosphere, and a recent study showed that two thirds of the energy made is wasted, released as heat and steam. However electricity generated in other ways can be green - and we will show you some of those for the rest of the week.
This set was issued in three colours, a) black, b) blue, and c) red. The red is very unusual and I am not sure it is as easy to pick out the details as it is on the other versions.
They also issued "See Britain by Coach" in the same year, 1954 - a set which was five years later issued by Gee`s Food, though I have a note to say that food might have been their main trade, but these cards were issued with Red Stripe Sweet Cigarettes.
The big question for you to work on is who was Blue Band ? Was it a company called Blue Band, or was it someone else who issued various packets of stamps with coloured bands to distinguish them from each other ? Or is this is question for our philatelic friends...?
