Park is from the "The Very Busy Life of Olaf an Venus" series by Canadian author Pierre Pratt. Sean checked this book out to read to Harriet because it has bright illustrations and is very easy to read (having only one word on each page).
With Pratt's background in magazine illustration it's understandable that the emphasis of the book is on the illustrations over the text. Frankly there a such few words the book could do away with all of them and not change anything.
Park reminds me most of the "Good Dog, Carl" books that Sean used to "read" in one of his previous day care. Park and Carl's Afternoon in the Park both tell a story of an adventure in the park through bold illustrations and only a smattering of words. Of the two, I prefer Park because the gag of the irresponsible parent gets old quickly in the Carl books.
