Mattel #6339 Uni-Tred and Space Bubble

#6339 Uni-Tred and Space Bubble Box Front

This combination set included the vehicles 6345 Space Bubble and 6346 Uni-Tred Space Hauler. The oversized box has truly impressive large, full-color graphics. I imagine that it would have looked fantastic on a toy store shelf. More information on the individual vehicles may be found in their own listings (links towards the bottom of the page). This set came with a unique set of 2-sided instructions, describing the workings of the two vehicles as a unit. Also included were the two sticker sheets (aka Space Labels) as shown.

John's Notes:

Released at the same time as the boxed Bubble and Uni-Tred, I find it unusual that the stock number comes before the individual boxed vehicle numbers (also in the Mattel 1969 "Fall" Catalog there's no "NEW!" label as there are for the individual vehicles, implying that the set may have been made available prior to the individual vehicle releases in 1969). I've always thought that this set should have had a "Super Action Set" version, which would have included an astronaut or two. It would be easy to imagine this combination, and there certainly is room in the box. The CIPSA version (link above) is worth viewing, as the Uni-Tred is maroon in color with differing stickers.
