On this post we have a rather playful FDC from Poland showcasing, you guessed it, children's toys! Issued on 01 Jun 08 in anticipation of Children's Day (20 November), this 2v set shows a choo-choo train and what looks like a xylophone. According to Poczta Polska, this is the second set of stamps issued with the theme of children's toys:
On June 1, 2006 Poczta Polska has issued the first part of the series of stamps with toys, unusual first of all because of their triangular shape. This beautiful issue presents a few universal toys, for the times unknown constantly developing children's imagination. On the stamps of 2006 issue there were the toys, based on the use of spinning motion, i.e. a top and a pin-wheel, while in this issue there are the kid's dulcimer and the wooden choo-choo train (on the stamps), and the playing ball and the rocking horse (on the FDC envelope). Toys can be seen in the triangular stamp frame only partially, in their entirety they are only visible on the complete sheet of 16 stamps of one kind. The occasional postmark applied at Warszawa 1 Post Office includes an example of one more toy - a horse's head on the stick.Also, this set is among the very few triangular stamps issued by Poczta Polska; the others were issued way back in 1959 (Polish Mushrooms 8v) and in 1963 (Polish Horses, 3 of the 10v are triangular). Others date back to the foreign occupation of Poland, in 1916 and 1918-1919.
The FDC was sent from Nowy Sacz on 27 June 08, almost a month after the date of issue. I guess Poczta Polska also allows use of FDCs with special postmarks even after date of issue, just like here in the Philippines.
