You rarely see stamps of these shapes, which only have become possible after we got self-sticking stamps that you no longer have to rip off a sheet along a holed line. And you rarely see stamps that feature such small botanical details as these two Finnish stamps of birch (björk, Betula in Latin). The young bud and then the seeds in their catkin, ready to disperse in the wind. Stamps really have changed, from the old time-consuming engraving and printing and licking, to the printed stamps from photos on sticky paper. I like both types, but I think the older are really more like art and these feel more like quick mass-production.
