For this tag, follow the Alphabet.
First person sends a card with an image starting with A, for example apple.
Second person sends a card with B, for example Brussels.
Third person sends a card with C, for example castle.
Fourth person sends a card with D, for example dog.
Etc… until Z is reached and we start again with A.
In case someone makes a mistake and doesn’t follow the alphabet, the next tagger can correct it so the tag can continue without trouble.
