It is for sure not the most valuable souvenir sheet. But is there any larger one ? This DDR (GDR) s.s.,issued Oct.6th,1964 measures 210 x 285 mm.
Not the largest souvenir sheet,just 76 mm high,but 237 mm wide. Issued in connection with 1947 Tokyo Philatelic Exhibition on May 15th. The s.s. was sold together with a ticket for the exhibition only. 302.100 were sold.A much higher quantity than that of several other Japanese s.s. of that time.The sheet needs very delicate handling and becomes folded easily.I guess a good number of them became damaged,before they could be stored properly.That might explain its rather high price.
