Israel Covers.. ID Help?

i have these three wonderufl Israel covers from 1979 in perfect mint condition. I was wondering if any one can help to ID them and perhaps a Cat value?







thanks for looking..

All three covers are of minimum value, the sort you might find in 50c-$1 boxes.

Nice covers though especially the Jewish Brigade Flag stamp ! [I would say that wouldn't I].
The second cover commemorates the 'Righteous among the Nations', those non-Jewish heroes who risked their lives to save Jews during WWII. The Holocaust Museum is inscribed on the tab.

You will notice all covers are dated Feb 13th 1979. Israel have always issued stamps in large doses about 4 times a year. That applies to present day new issues as well.
