Morphology
The literal idea of putting a reply on a postcard is directly derivable from the constituents 'answer' + 'on' + 'a' + 'postcard', so a learner who knows these words will grasp the basic sense. However, the phrase is a conventionalised (chiefly British) and often humorous way to request a brief or informal response, a pragmatic nuance that is culture-specific and not fully predictable from the parts alone.
Etymology
Answer on a postcard comes from old British magazine and radio competitions where readers were told to write an answer on a postcard and send it by mail. Because a postcard is small, the phrase became a playful way to ask for a short, informal reply, so today people use it to invite quick suggestions.
