A completist wants a complete set. Collectors are addicts. I want every Steinweiss record cover I can get, and buy every one I see at a reasonable price that is in decent condition.
Here are m560-m564 complete, plus m566, m567 and m569. Many of them are mm not m by this point. Great designs in my opinion, Steinweiss was at his peak at this point, right after (I think) WWII.
