This card having a picture of a painting by Siri Derkert was sent to Hsin-Yi.
I and my daughter visited Siri Derkert's exhibition in Sweden this summer and I bought the card from there.
I hope Hsin-Yi has already received my card though I forgot to add the priority label on it!
This is what is written in Internet about the exhibition:
Siri Derkert (1888–1973) is a pioneer of Swedish 20th century art. Her early cubist paintings are attributable to international modernism, while her later work for the Östermalmstorg underground station (1965) in Stockholm marked a radical change in the notion of public embellishment.
For the first time since 1960, Moderna Museet is featuring Siri Derkert’s unique and multifaceted oeuvre in a major retrospective exhibition. Works from her youth, cubist paintings, fashion drawings from the 1910s, profoundly psychological portraits of children and adults, drawings and later experiments with materials such as concrete, iron strips and clay – all presented in a generous show that also highlights the life of Siri Derkert. Her works for public spaces often deal with the peace movement and feminism – issues that are as relevant today as they were for her generation.
