President Shimon Peres posted to Facebook pictures showing the disguise he wore when he travelled to Jordan to meet with King Hussein in the 1970s - more than a decade before a peace treaty between Israel and Jordan.
"Purim is a great time dress up but not the only time," President Shimon Peres wrote on his Facebook page on Friday afternoon, a day before the Jewish holiday begins.
"The beauty of Purim is that it brings out the creativity in us all in celebration of a holiday that is all about fun!" Peres wrote.
In the pictures he posted, Peres can be seen wearing a mustache and beard, horn-rimmed glasses, a wig and a fedora.
He asked his Facebook followers to share pictures of their costumes, which "I am sure they are much better than mine."
