It was probably as clear as daylight to you more experienced smurfers, but I inadvertantly bought my first fake (see picture). This was from fja13's free-for-all.
The heart-o-gram, while the correct shape, was smooth and was colored (on both sides) with magic marker. I've never seen the smurf up close, and thought that was how the back looked. Fja13 did a good job positioning his smurfs to hide the rubs (though I'd already detected a few here and there and expected them not to be in perfect shape).
How do you recommend I rate him? I guess a green, but with the comment "one smurf was a fake"? He's probably not worth getting into a rating war with.
I'm tempted to pry the heart-o-gram out with an x-acto, then at least I'll have the mate to Congratulations Smurf. What a way for him to wreck a good smurf!
