#1 turns up on eBay UK occasionally. One sold for £35.56 in Nov 2007 in what looked like a FN. Another nice looking copy of issue #1, around FN , sold for £51 on eBay UK in Dec 2009.
Amazing that the annuals lasted so long! They started in 1971. I have a copy of 2008 but not seen a 2009, 2010, 2011 so I guess they have stopped now.
18th May 1991 1st Mandy and Judy...but it didn't last long....
Note: some PR issues may have no value. Selected issues in FN, VF or VF/NM may not exist in some titles.
