They do look Jollyfine up close.. The bottom one is advertising Tea, but the other two are for Pantomimes, a yearly Christmas time tradition over here. All are stone-litho from the mid/late 30's, they may have used the same design for a couple of years, as these were generic posters, to be printed off as and when. I've only ever seen two (inc this one)of the Robinson Crusoe in this size, glad to get it.
Most of the Robinson posters from this time would never be aloud now-a-days for obvious reasons... They do capture a bygone era.
