Peek-a-Boo Valentine Girl in a Bonnet — Vintage Postcard

A reproduction of an antique “peek-a-boo” Valentine postcard: a child in a ruffled bonnet and red-and-white dress raises both hands beneath a heart-shaped portrait window, inviting the sender to take a look and guess whose face turns up.

• Density: 350 g/m²
• Size: 10×15 cm

Because the portrait window doubles as a tiny frame, some collectors keep this one rather than mail it.
