Book from 1940's, illustration of boy with beret holding large box that says "try our large economy size" possibly from nyc

Pretty much the title description is all the info I have. Could be published in new York or take place there. The boy may have had curly hair. This is a book my elderly aunt is looking for and there wasn't any more information than I've offered

Probably solved now. Idk how to change the tag. Thanks for the help
