A list of stamp shows in Southern California can be found here:
http://stampshows.com/california_s.htmlI have no idea how exhaustive this list is.
Have a thick skin, because most dealers will be pretty dismissive of these. Hopefully, most won't be outright rude, but, you could see a little bit of that.
You'll see that some dealers will have banker's boxes for sale for $10, $20, $30-ish dollars that might have several of these types of albums, along with some old reference material, pages from old albums, envelopes full of stamps. Some people like to buy these types of "variety" boxes.
If they aren't interesting to you, perhaps there is a kid in your orbit who would find them interesting?
