The crown is that of Yehuda, which Yaakov's bracha says shall not leave his line. It is also the crowns of David and Shlomo, from the Haftara.

The crossed hands are Yaakov's from the bracha to Ephraim and Menashe.

The water dripping from the tap stands for Reuven, water being mentioned in his bracha. The lion cub is Yehuda. The ship is from Zevulun's bracha. The donkey is for Yissachar. The snake is from Dan. The fat bread in the lower right corner is from Asher's bracha. The wolf is for Binyamin. (Binyamin Ze'ev is a common combinationof names, taken from Yaakov's bracha to Binyamin.) The symbol of the Israeli Postal Authority is the swift deer from Naftali's bracha. And back to the lion, we find that Yehuda Leib is a popular name-pair.
