By the Sea is a sunny and happy painting, which makes this puzzle delightful to work, for adults and age appropriate children alike. The animated colors are fun and distinct....making it easier to sort them for working. The artistic design and cut of this puzzle is truly imaginative. Looking at the patterns, seen within the finished puzzle, brings to mind bubbles blown by a child's bubble wand....with all of the bubbles floating up, around, and over each other. The pieces are very creatively shaped, are sturdy, and fit nicely into place. Some pieces are curved, but they all have circular "bubble-like" connectors. The numerous whimsies are charmingly designed, and perfectly reflect the scene of the painting. I've worked this puzzle several times by myself, as well as with my sons. Both boys were instantly hooked by the shape and feel of the wooden pieces, amazed at the level of detail, and they really loved separating out all the whimsies. Even after all of the fun I had working this puzzle myself, it turned out to be a great family puzzle as well...a win on all counts!
