Winter Wrap Up is coming, and in Ponyville every able bodied stallion and mare must do their part. Tradition demands that citizens do without magic, and just in case you forgot, posters plastered all over town drive the point home - Use Hooves, Not Horns, and wrap up winter the earth pony way.
Someone requested that I do an homage to Abram Games' Use Spades, Not Ships
with ponies. [link]
The original poster, commissioned by Her Majesty's Stationery Office, implored British citizens to grow their own food and rely on domestic production, rather than having food and supplies shipped to the island nation. Ships were vulnerable to German U-boat attack, and countless tons of food were lost to sunk ships. The message was effective, and Britain's increased self-reliance helped them through the war.
