I wholeheartedly agree.
I don't think anyone really bought these for their collectability so much as they did for the awesome illustrative style that Ken has harnessed.
I only learned of them much later and sadly missed the boat on #s 1&2. I've admired the ones on Rob's wall pictured earlier and will be purchasing #3.

These are pieces of art that any and every pinball fan should have the opportunity to hang on their walls.

I echo the comments of many others here in hoping that they can, once again, be made available and in greater numbers for all of us to enjoy. I'll live without the limited numbering or signature... just give us this great art!

Thank you Ken!
