Adorable set of Vintage Blocks. A squeaker is in each! Made from cardboard. Marked "Made in Japan"

It has great vivid color and classic animals graphics such as a poor puppy dog "tiffing" with a kitty cat, kitties with bows and milk, monkeys riding a tricycle and playing on a see saw, a baby elephant sitting on an ice block, a baby lamb with a butterfly, a squirrel with his nuts, and a bear cub and a robin, a musical bunny, a happy family of ducks and ducklings, a cow with a bird on her bum, and a pig with a duckling friend. All with short beginner friendly reading phrases explaining the pictures.

The biggest block measures 4.80" tall x 4"wide, the 2nd largest block measures 4.80" tall x 4"wide the 3rd largest measures 4.5"tall x 2.5"wide and finally the smallest measures 4.25" tall x 2" wide. All sizes approximate. Each has a place on the block where a squeaker is inserted in the cardboard and behind the paper so baby can press or pinch it and it will squeak. Each has a slightly different squeak and I'll tell you it is ADORABLE!

All are in fair to good condition with expected wear on the edges of the paper that covers the cardboard frame of the nesting block. They nest together making one block if desired as they are hallow on the inside. The condition is shown in the pictures. As you can see in pictures, there  are places on the blocks where the cardboard is separating. Mentioning to be accurate and clear.

I have never seen anything like it. What a unique find! Only have 1 of these, make them yours.
