Cranium Dispute

[Rexmons]

First, I just want to say if you have not played the game you are missing out. For those of you who have played here is my question:
My team ended up getting a Sensosketch (Pictionary with your eyes closed) my word was "Unibrow" and this is what I drew:

The other team said my picture did not count because the arrow pointing to the unibrow is clearly a symbol and there's no symbols allowed. After some debate, we chose not to count the picture. The next round was a Club Cranium Sensosketch (same thing but both teams play simultaneously against each other). The word was "Vending Machine" and the other team got it first. When I asked to see the picture their teammate drew for them, this is what they handed me:

I challenged the card on the grounds that they also broke the rules by including the number 1 on the dollar bill. The other team firmly believed it was within the rules to do this because the number one did not constitute a letter or a symbol. The debate went on for over 10 minutes and became heated at times. If you are familiar with the game rules, I would be interested to hear your input on the subject.
