For the Sunday Stamps of orange and/or yellow theme this week, I collected from the stamps from the envelopes of letters sent by my Finnish pen pal.
I rarely receive stamps with uneven perforation outlining the design and these two sunflower stamps are among them. The stamp on the lower left is an artwok of the realist Helena Schjerfbeck. It's 1 of 4 stamps issued to commemorate her 150th birthday.
All stamps were from 2012.
