In 2007 Ridgewood Stamp Sheets produced a customised themed Charity Smilers sheet to raise money for Red Nose Day - 16th March 2007.  It was sold exclusively on B1D and all proceeds raised (£1,000) were donated to the charity.    

50 sheets were printed but not all sheets sold on B1D and so as a thank-you the balance were overprinted with a different design and sent to all purchasers of the original sheets as a thank-you for buying the original sheet. The "Big, Red, Thank-You Sheet" is accompanied by a copy of the certificate issued by the charity following the donation.
