Union Jack

 The Union Jack, or Union Flag, is the national flag of the United Kingdom. The flag also has an official or semi-official status in some other Commonwealth realms; for example, it is known by law in Canada as the Royal Union Flag.

This little card was apparently a trading card that was issued by BOVRIL LTD in the 1930's. It unfold into three sections featuring the Flag of St George, Cross of St Andrew, and the Cross of St Patrick.

You can read a little bit about it on the back of the card. The red cross portion flip up, while the red and white X can be totally remove, turned over, and is all red.

Bovril is the trademarked name of a thick, salty meat extract developed in the 1870's by a Canadian named John Lawson Johnston. You can dissolve it in hot water and make tea. As the card says, "Bovril" is British to the backbone. Bovril was used to help feed troops during several campaigns and you can see the ads for Bovril with the "Bovril" Bull standing outside an army recruiting tent with the tag line "Bovril recruits its strength from the power of beef". So this was a fun way to advertise and be super patriotic all at once. Pretty cool history.
