This is a vintage Junior Elf Book

The Roman Numerals say MCML (inside front cover, see photo) which is 1950

BUT there is a upc symbol on the back which were not used until the 1970's??

So, I am a bit confused...lol

The cover shows shelfwear and dings. Original price was 39 cents.

But inside, it is almost pristine. Inside seems unread with pages feeling new and not falling open, tight and perfect.

The last page, in photos, shows the glue coming loose.

Thanks!
