Architecture for Humanity understands that for design lovers, a good greeting card (among other things) is hard to find. And so the nonprofit is kicking off its annual “I Love Architecture” campaign with a selection of e-cards that allow senders to simultaneously declare their love for the recipient and one of eight iconic structures, from the Taj Mahal and the Eiffel Tower to Herzog & de Meuron‘s Beijing Bird’s Nest and the Castelvecchio Museum, renovated by Carlo Scarpa. The buildings were selected because they are emblematic of architecture’s unique “merging together of learned skills and individual practice,” according to Architecture for Humanity co-founder Cameron Sinclair.
