Vintage Victorian Forget Me Not Card with Cherubs & Heart

What prompts two chubby cherubs with rosy cheeks and tiny iridescent wings to abandon Cupid's arrow entirely in favor of a full brass cannon mounted on a blue carriage? Apparently they've decided that firing a flaming red heart into the sky while a pile of spare ammunition hearts sits heaped on the ground below is the superior romantic approach. One cherub mans the cannon with authoritative swagger while the other covers his ears—a completely reasonable response to artillery discharge that no Valentine's card has ever had to address before. The script reads 'Forget me note,' which is either a charming pun or a barely veiled threat depending on how you feel about receiving weaponized affection from rosy-cheeked toddler war criminals.
