That's a nice, well-rounded collection.
And you've got a few puzzles in there (like the Latch Cube) that can't easily be found anymore.
Thanks. And yeah, with the Latch Cube I was lucky. I bought it from hknowstore and after I bought it they were out of stock.
The rest are pretty common I believe, except those two picture 15-puzzles, those are from the 90's and a gift from my Grandma.
And the Animal Picture cubes were from a shop nearby here in The Netherlands, so I believe they might be hard to come by for the average former Cube-Collector.
