Cool basket, good luck in the search!
I possess tons of MCM goodies and I've identified quite a few patterns by searching storefront sites like Etsy, and Bonanza (and others). I stumble into my finds by changing keywords in the search. In one instance I found chip-n-dip glassware that matched a set of drinking glasses I was going to post to Craigslist at which point I spent money rather than selling.
Another time my mom asked me to find her lone piece of Pickard China pot online. Didn't find a match but found the matching cream and sugar for cheap. I think she was going to consign some items, having the match made a difference...
Wire planter, wire basket, vintage basket, antique planter basket, wire flower box etc., just never use the same keywords twice once you're on a roll.
