Not in my Album - Tete Beche 4

This is the last of the uncommon Tete Beche stamps issued. This is the Freedom from Hunger Tete Beche sheet issued in 1963 (Scott 237). This stamp was used in the twelfth booklet Israel produced, and is much rarer than the previous issue (the zodiac Tete Beche stamps, which I skipped over so far). I don't know why this one is so much harder to find then the zodiac sheets, or even why the vertical gutter pairs are harder to find then the horizontal Tete Beche pairs. There are 4 of each on the sheet, so you would think that they would all be worth about the same, but for some reason the vertical pairs go for much more than the horizontal ones.
