The Spalding Sports Co. Of America cards are easy to obtain as a type card. Going for the whole set would be very challenging. Since they were issued in little opaque envelopes, and obviously saved that way, many can be found in high grade. As mentioned there are some hand cut ones from ad sheets too. The ones I have seen like that are blank backed. And lastly the 1927 Copyright Babe Ruth examples are somewhat of an anomaly. When the first 1-2 came out they were very expensive (which is when I got mine of course). Then the next one-two went for less than half of the first one. That's the way the rare cookie crumbles. Win some, lose some.
