Stadium Club is a series of baseball card sets from Topps. The first set was introduced in 1991 as a high end response to Upper Deck and their (perceived to be) superior products. After 2003, the set was no longer produced and some of the insert themes were integrated into other products. Topps did release an additional Stadium Club set in 2008. In 2014, Topps began to release the line annually once again, this time as a mid-level product.
