10 Sept 1942 homemade wrapper endorsed "Book Post" in manuscript from Barwani City to Rajpur franked with 1/2a blue-green (5th printing) tied by "BARWANI / 10 SEP 42" cds. This is one of only two known Barwani printed matter wrappers to the exhibitor. It proves that the postage rate for book post was half that of ordinary letters
