Paint by numbers was conceived in 1949, in Detroit, by two people who are usually credited separately and should not be. Max Klein, an engineer who owned the Palmer Paint Sales Company, and Dan Robbins, a commercial artist working for him, developed the format together. It sold under the Craft Master name, and Klein sold the Craft Master business in 1959.
The Smithsonian's National Museum of American History holds the Craft Master papers, which is the reliable source for all of this. You will see 1950 and single-inventor claims elsewhere; they are wrong.
Why it took off, and why it was resented
The early 1950s was the right moment. Postwar households had new walls to fill, more leisure time than the generation before, and no tradition of buying original art. A kit produced something frameable for a few dollars.
It sold in enormous numbers, and it drew genuine hostility from the art world — the objection being that it handed people the appearance of painting without the substance. That argument has never really gone away, and it is worth engaging with rather than dismissing: a numbered canvas is a craft object, not an act of original expression. Most people who paint them know that perfectly well and are not confused about it.
The cultural verdict softened. Craft Master kits are now museum objects, which is its own kind of answer.
What the vintage kits looked like
Recognisable by their subjects as much as anything. The classic Craft Master catalog ran to:
- Pastoral landscapes — mills, streams, autumn woods
- Horses and stags, everywhere
- Religious subjects, The Last Supper above all, which was the period's single best-selling design
- Harbour scenes and clipper ships
- Matched pairs, sold to hang either side of a fireplace
Technically they were different from a modern kit in ways that mattered. Many used oil paint rather than acrylic, in tiny tins, which meant long drying times and solvent for cleanup. The support was often academy board or heavy paper rather than stretched canvas. The printing was engraved or screen-printed and the section outlines were heavier — a period kit tends to show its lines more than a modern one.
Collecting them
Sealed, unpainted kits in a complete box are the collectable item. Values are modest for common designs and rise for unusual subjects, complete matched pairs, and anything with original packaging in good condition.
If you are buying one to paint rather than to keep, be realistic: seventy-year-old oil paint in an unsealed tin is almost certainly unusable. Buy it as an object. Modern acrylic kits exist because the medium is better suited to the job.
Finished vintage paintings are a different market — plentiful, cheap, and increasingly collected for their own sake as period objects. Some are genuinely well painted.
What modern kits inherited, and what changed
The core idea is unchanged: reduce an image to flat numbered regions and supply matched paint.
What changed is the execution. Acrylic replaced oil, which is why a modern kit needs only water. Digital conversion replaced hand-separation, so designs can be far more detailed. Pre-stretched canvas became standard for framed kits.
What has been lost is arguably the artwork. The Craft Master designs were painted specifically for the format by staff artists who understood how it worked. A lot of modern catalog is generated automatically from stock photographs and shows it. Kits built from licensed original paintings — ours are, from artists including Kim Norlien, the Hautman brothers and Judy Buswell — are closer in spirit to how the format was originally made.
Common questions
Who invented paint by numbers?
Max Klein and Dan Robbins together, in 1949 at the Palmer Paint Sales Company in Detroit. Sold as Craft Master; Klein sold the business in 1959.
Are old paint by number kits worth anything?
Sealed complete kits in original packaging have modest collectable value, higher for unusual subjects and matched pairs. Finished period paintings are plentiful and inexpensive.
Can I paint a vintage kit I found?
Probably not. Oil paint in unsealed tins from the 1950s has almost certainly cured solid. Treat it as an object rather than a project.
What is the difference between vintage and modern kits?
Vintage kits generally used oil paint on board or paper with heavier printed outlines. Modern kits use water-based acrylic on pre-primed canvas, with finer detail from digital conversion.
