I'm in the process of cleaning this ladies land and when going through all the rusty junk metal there is like a whole ditch with bottles. Here is a picture of what I got cleaned up so far. Just the out sides are clean for top get a brush or sponge for the insides.I believe they are 60s late 50s and up. After I get them cleaned up more I will be putting them on eBay unless anyone is interested I will be having more pics soon.
