Remember the Lirah?

Before Israel switched to shekels, it used "lirot"-- the Israeli lirah. I was reminded of this when I reupholstered some chairs I found on www.yad2.co.il  and found these tax stamps on the base:

These stamps probably date the chairs to at least the 1960s, but I found someone selling an almost identical luxury tax stamp on ebay claiming that it was from 1951. (The stamp was selling for 24 dollars! Too bad I already covered these ones up!) I'm pretty sure that ל''י is the EARLIER abbreviation used for the lirah, before Israel switched to a symbol similar to the British pound in 1955. Can anyone confirm this? Can you help me date these tax stamps?

At any case, I love the chairs. Here they are pre-reupholstry:

I'm pretty Zeus preferred them when they were grimy and worn, as in the picture above.

Can anyone identify them? I think they're Yugoslavian versions of Danish Modern furniture, but I'm not sure. By the way, I'm discovering that flea markets in Israel aren't great for finding really old antiques but are awesome if you like midcentury/Danish modern-- a whole lot of people moved here in the 50s and had to buy everything from scratch. This country is also a treasure-trove of 70s decor... let's hope that becomes trendy. :)

Anyway, here's one of the chairs post-sanding and reupholstery. The new fabric is micro-suede because that's the only thing our cats have trouble destroying. I stained the wood to a reddish shade (sorry, purists!) to contrast more with the fabric. I'm still getting the hang of reupholstery, but I'm happy with how this chair turned out!

Good times. (Can you tell yet that I'm a little obsessed with decorating and furnishing our new apartment? Too bad we don't move in until April!)
