Thanks to all for your suggestions, I will waltz thru them to see what I kick up :)
Emily, you are a wealth of info/Vienna - thanks especially for the 'FlohMarkt' info, even tho disappointing. There must be smaller neighborhood Floh markts elsewhere. I will research that and all of your excellent links.
For those of you ineterested in other European flea markets, here are a few I have really enjoyed:
The best street 'flea' markets I have experienced in Europe are:
*Dresden - a 20 minute walk down the river, early Saturday mornings. Yes, household junk, but most of it useful especially if you are looking to set up a household, and also lots of wonderful old stuff/bric-a-brac, including a fair amount of WWII memorabilia from both 'sides' - and - good condition mid-century household electronics made in Germany = excellent, and fun to explore.
*Krakow !!- Superb Saturday flea market - everything from soup to nuts (literally - excellent market food vendors, too!) - and - on Sunday, clothing/accessory market with gently used and mostly excellent quality items, plus a bonus: some fabric artists selling small things that made wonderful gifts - handmade - from seller to recipient, at fair prices.
*Budapest - I almost fell over when I saw this market - everyone just plots their stuff on blankets, all along the park's walkways, rtoo much to see !! - art nouveau jewelry/bric-a-brac, beautiful old boxes made from any material imaginable, metal objects etc-- got a pair of gently used Soviet era binoculars, and a few more things. Highly recommend, allow at least 4 hours (or as much time as you can stand). We were so worn out when we finished, we walked to the thermal baths in the park and soaked for 2 hours. ...Lovely day :) -- I would go back to Budapest just for this market alone - but it is also a great city to visit - very friendly people, did ot have enough time there. I would do more thermal bathing next time, it's wonderful.
*Paris - not the huge (altho perhaps interesting) monstrosity on the North side that is extremely crowded/expensive and sells mostly large antique/designer household furnishings, but the smaller and totally wonderful Puces de Vanves, easily reachable by Metro (Porte du Vanves) on the South side. ..blocks and blocks of vendors, mostly selling small goods, anything you can think of, and many things you would never have thought of! - I scored some wonderful old beads, a small WWII US military issue hygiene kit for men (shaver, mirror, with all accessories-very compact) for my son - he collects, ---and other bits that I could fit into my suitcase, including a few vintage jewelry working tools (for manipulating metals) - have never seen anything like that at a market before.
That's a market 'wrap' - :)
Hope i can find a quirky neighborhood market in Vienna - thanks again, to all ---
