1919 WW1 Painted Hearts by Lehmann Valentine Postcard

1919 vintage postcard. A charming illustration of a child in a sailor suit painting red hearts on a garden wall. Red roses, the traditional flower of romantic love, grow off to the side. Artist signed by Lehmann. The ink shortages during The Great War limited postcards to one and two-color, simple designs, as seen here. Postage was raised to two cents to fund the war effort. 

Valentines Greetings
To you, I post, My heart to-day,
And this is how, Love finds a way
