More Key Lithos

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
The Playroom

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:

Skateboarding Andy:

These are the 28 key lithos I know about.  Please let me know if you find a different one!
