This sticker comes from the 1963 Topps Peel-Off insert set. As you can see, the front has a floating head picture of the player, along with a listing of his team and position.
There were a total of 46 unnumbered stickers in the set. Banks was one of two Cubs in the set; second baseman Ken Hubbs was the other.
I would assume that these would be more scarce than other inserts of the era, since many of them ended up getting stuck on notebooks, book covers, and other assorted items.
If you're wondering who else the set included, here is the checklist, sorted by team.
|Bob Aspromonte||Colt 45s|
|Dick Farrell||Colt 45s|
|Bill Monbouquette||Red Sox|
|Carl Yastrzemski||Red Sox|
|Luis Aparicio||White Sox|
|Ray Herbert||White Sox|
|Floyd Robinson||White Sox|
