Liz, your photo reminds me of my cousin Simon who lives in the Netherlands. He collects elephants and has quite a number of them like yours. He too has an apartment full of them.
As a general rule, I don't care much for ornaments simply because they are require dusting and I like to minimise the amount of housework I am obliged to do! (

). Ornaments are always referred to as "dust catchers" in our house.
However, I attended an auction recently and bought the cute little cat ornament below simply because I liked it. In fact, I bought two from this series. There were quite a number of similar lots at the auction which had obviously come from a shop that had closed down because the ornaments were still in their boxes and had never been used. They come from a range called "Comic and Curious Cats" by Linda Jane Smith. I was told they were "collectables".
I paid $15 each for them. When I got them home, I discovered the original price tags on the bottom - $195. I have subsequently seen them in gift shops for the same price. So I was quite pleased with my bargain buy.
