That is a cubit or so wide and high!
Brilliant observation, Jimbo!
According to the info on playmobil.de the pyramid measures 53 x 53 x 35 cm (or approx 21" x 21" x 13.75") and, according to wikipedia, the ancient Egyptian Royal Cubit was 52.35 to 52.4 cm (though the standard today is one cubit = 18" or almost 46 cm.)
Is this merely a lovely coincidence?
Thanks for the new pix Richard & Andi!
