I would have liked the pink enamel, but too expensive for my little purse. I have one like the egg-and-dart, without the "To Mother."
Simons Bros. Cherubs and Garlands thimble.
US$24.99; 1 bid.
12 March 2007.
The listing for this item showed other photographs of the thimble, including one showing the inside of the thimble and the Simons Bros. mark. It appears to be a genuine Cherubs and Garlands thimble. I think the really low selling price for the thimble is due to the huge holes (shown in photo to left and noted--as small--in written description in listing) in the thimble and possibly the proliferation of reproductions of these thimbles that I have previously mentioned.
14K Gold Thimble with black enamel floral design around band; inscribed "Kate," size 8, in-round, enamel not chipped.
US$225.00; 10 bids starting at US$9.99.

8 March 2007.
The seller listed this item as have been made in England in 1479, based on the markings on the thimble: "A big ( A ) then ( I ) also ( 750 ). A bidder (?) submitted a note stating that this could not possibly be from 1479 and that it was more likely of German manufacture, ca. 1875-1890.
