Three of my favourite stamps of all time were used here. This set of five stamps was issued for the 20th anniversary of the Simpsons on 7th May 2009. These stamps actually turned out to be a desaster for USPS. 1billion were printed, but only 318million were sold. Reasons were most likely that way too many were printed and that these are 44 cent stamps and not Forever stamps. That resulted in the destruction of the remaining stamps when prices were increased. I have a complete set of them in mint condition and also got Bart and Lisa on a card years ago, so it is great to finally have them all on cards as well. Next up I should try to get a complete sheet or a set of FDCs. You also have to watch the episode of Exploring Stamps that Graham Beck has done about them. It was the first I had seen and it immediately got me hooked.
Thank You very much Audra!
