Beverly Cleary Henry and Ribsy 1st Edition?

This Henry and Ribsy 1954 First Edition is different from the ones that are for sale.
Henry Huggins: Henry and Ribsy by Beverly Cleary (1954, Hardcover)First edition 9780688313821 | eBay
This ebay one is red board with dust jacket, 5.6" by 8"
Mine measures 4" by 7" the cover illustration is printed on the board. BTW mine is signed.


Is mine a first edition and why is it smaller that the other one?

 

Looks like a library binding.

ISBN numbers weren't introduced until 1967 ('68 in U.S.).
