Crochet Jiffy Motif Bedspread No 415

Jiffy Motif No 415:  This pattern gives directions to crochet the motifs pictured.   The primary motif, measuring 5 inches is joined with a small fill-in motif.  Create and join motifs to bedspreads or other household accessories. The design is worked in Crochet and Knitting Cotton.   This Royal Society pattern is not dated, but based on paper and style I'd suggest 1940's.  

Materials:  For a bedspread about 70 by 110 inches, 23 balls (400 yards each) knitting and crochet cotton; steel crochet hook No. ??   (Note:  the size hook was not readable on leaflet).  

For a bedspread about 90 by 110 inches, 29 balls same cotton and same hook.
