This is one more postcard I found in St Ives. I researched a bit but I couldn't find any information about the woman pictured or the costume she is wearing.
On the back it reads: 'Many thanks for card, was pleased to hear you have so many cards. I have not counted mine lately.
The postcard was posted on 16 December 1905 at 8:30pm from Market Drayton with a half pence stamp picturing King Edward VII. Stamps for King Edwards reign were issued on 1st January 1902 until 1910. The inland postage rate for postcards was ½d (halfpenny) throughout this period.
Market Drayton is a market town in north Shropshire, England, close to the Welsh and Staffordshire border. It is on the River Tern, between Shrewsbury and Stoke-on-Trent, and was formerly known as "Drayton in Hales" (c. 1868) and earlier simply as "Drayton" (c. 1695). In 1245 King Henry III granted a charter for a weekly Wednesday market, giving the town its current name. The market is still held every Wednesday.
