The artwork for Pansy Potter in Wonderland was by James Clark. The Wonderland theme ran until November 1953 when Pansy returned home. Here are a few examples of the series from the middle of its run in 1950 and 1951. (The colour hasn't faded on these pages by the way. It was only printed in red, yellow and black.)
The artwork and the comedy sequences remind me of animated cartoons of the 1930s, which may have been James Clark's inspiration for all I know. In that regard it perhaps looks a bit old fashioned for 1950, but it's a busy and fun strip all the same. The following strip features a soap-box cartie, the vehicle of choice for many characters in British comics over the years of course!
Pansy Potter appeared in Sparky comic from 1965 for much of its run but returned to The Beano a few years ago where she still appears from time to time.
