I have a small collection of 2 (is 2 a collection?) vintage paint-by-number poochs that guard my kitchen.  The German Shepherd Dog I bought because I love that breed and have been lucky enough to live with a few. 
But this collie mom and her puppies I had to buy..
because of what was on the back:
Awwww.....can you stand it?

Barbara Jean, we know the herculean task that lay before you when you got your kit some 50 years ago.  Many of us tried a paint-by-number (me, I attempted a praying Jesus), but few of us finished.  But girl, YOU DID!  8:30 P.M. you put on your last brushstroke, probably past your bed time.  You deserve to feel very proud.

Barbara Jean, your paint-by-number dog portrait is still well loved 50 years later! Thank you so much.

Did any of you make a paint-by-number?  I think they are still available on Ebay!  I don't know if they are new or vintage, but I think I'd rather knit!
