Long rectangular box in 1900 embossed metal with children and birds

Very representative of the beginning of the 20th century, with a drawing which represents 2 children, a girl and a boy releasing birds from a cage. 

The birds have gathered in lines that look like musical staves.

Approximate dimensions: length 19 cm, width 7 cm and height 6 cm.

Note, lacks in the paint and deformations due to its great age.
