LEGO 4695 Mini Harry Potter Knight Bus was a 58 piece Harry Potter promotional set released in 2004. This set was never available in retails store, but was available from Shop At Home with the purchase of the 4755 Knight Bus (or select 4757 Hogwarts Castle) as well as being subscribed to Brickmaster at the time and receiving it as the monthly gift. Also, in select movie theaters is was given away with tickets to the Harry Potter and the Prisoner of Azkaban. Check my sellers list for more Lego sets. Buy multiple sets & get a better deal. I will also trade for Lego Star Wars, Lord of the Rings & The Hobbit sets. Please email to arrange your purchase. Thank You. š·
