1956 Topps Baseball was the first set I collected as a kid buying nickel packs, although Mom cleaned house when I went away to college.
When I reintroduced myself to the hobby 35 years ago, my first objective was to put a 1956 Topps set together again. I have sold the majority of that set now, but still have the Mantle, Robinson and Clemente in decent grades and a few others. I would post scans, but mine is nearly identical to the cards already posted in this thread.
The '56 Topps set is numero uno in my book. It even has a
George Zuverink card. What more could you ask for?
