A variety of postcards are available throughout Israel. Some fun. Some serious. Some religious. Some touristy. Something for everyone.
When I first came to Israel in 1990, I made my own postcards out of Kellogs Corn Flakes boxes. Some of them made it to the US, others didn't because they weren't the official size and type of postcards.
All these in the photo are official size, so you can expect them to arrive at their intended destination . . . assuming they have proper postage.
