The books I have in mind are a series of wordless picture books that were probably published in the 80s or early 90s. While they weren’t graphic novels or comic books per say, the images were arranged in panels on each page and you’d “read” it by following the story from left to right, top to bottom. The stories centered on a family of rabbits (or I’m pretty sure they were rabbits, they might have been mice) and there were books for each holiday—the ones I remember most vividly was the Halloween book and the Valentine’s Day book. The rabbits were anthropomorphic and were shown putting on coats for fall, trick or treating in a neighborhood, and so on.
I can still picture the books in our elementary school library and so the author’s name must have come closer to the end of the alphabet, since I remember them being nearer to the end of the shelves—possibly in the R, S, T section?
