In my previous post about key lithos I calculated that there are 28 different Precious Places key lithos. The website ThisOldToy.com has pictures of 21 of those lithos. In addition, I have previously posted pictures of the key lithos for these three sets (click on name of set to view images):
The Sunshine Country Picnic
The Pretty Penny Wishing Well
Just to complete the library of litho pictures, here are the last four:
The Best Friends Pet Shop:
The Pink Slippers Ballet Studio:
The Tip Toe Gymnastics Show:
These are the 28 key lithos I know about. Please let me know if you find a different one!
