Tiger Cycle - Made in Holland - 50's Vintage??

I got this bike from my father in-law. Its a "Tiger Cycle" and it says "Made in Holland". I would guess it to be built in the 50's. Its in fantastic shape and still works fine. Tires need to be replaced it could be ridden anywhere! If anyone has any info on this bike, please share. Is this a rare bike? Quality? Whats the value? I was thinking of restoring it myself just for the fun of riding it, but I dont want to ruin a valuable bike (im not a bike restoration expert). You can email me with any info too. austrianoakjr@yahoo.com
