I bought the animal alphabet puzzle from a vendor in London while I was visiting there in 2015, before I was married or had children, knowing what a delightful heirloom toy it would be for my someday family. On that occasion I also bought the train puzzle, the elephant counting puzzle, and the tree puzzle for my sisters and mom, then hauled them all back to America in my suitcase! These puzzles are beloved by my family (I now have two daughters of my own, and they have both played with our animal alphabet since before they were one. My husband and I enjoy doing it with them as much as they do, which is a real compliment because generally playing with their toys is a bit boring for me!). Note that this particular puzzle is more challenging, which means it will serve to entertain children both young and old (the young with assistance, the old more independently). The elephant puzzle and the other counting ones are easier for younger children to do on their own. These puzzles are treasures! I can't recommend them highly enough!
