In the 2004-2005 time frame, Upper Deck issued one of the more unique collectibles in recent times from a major manufacturer. Dubbed the Jox Box, these are player themed jack-in-the-box toys. I'm not sure why Upper Deck thought these would be popular as you don't even see traditional jack-in-the-box toys for sale very often anymore. But they did their best to produce pop-ups that resembled the featured player enough to drive some demand. Suffice it to say, demand was not very high and these have been relegated to the bottom shelf of history.
For Cubs collectors, we received more than our fair share of the players in this set. The checklist I have seen for these toys has 17 players on it, which seems like an odd number of subjects. But I guess that oddness fits well with the toys themselves. Three of the players in the set are Cubs, with Sammy Sosa, Mark Prior, and Nomar Garciaparra representing the North Siders.
Nowadays, these are not very hard to find online and can be had fairly cheaply. The problem is with the cost of shipping as there aren't many cheap shipping options for these. Getting one for less than $10 shipped is a challenge and that is more than I am really willing to spend on these. If I could find the trio of Cubs for about $10 total including any shipping charges, I would probably grab a set.
