The slide puzzles come around rarely. Maybe a couple times per year. In the last 10-12 years I have seen about that number.

Now the colorform box is another story. I think I have seen exactly 2. Once, I forgot to bid and it went for about $6 - that was close to 10 years ago - back when there seemed to be much less oddity collecting pressure. The last one I saw was maybe 4 or 5 years ago and it went for around $100 iirc.

I am not a collector of such items, so I do not go out of my way to look for them. But both are odd enough that I do take notice.
