First reflective use ever on any licence plate!

Camera flash shows yellow reflective beading.

Quad-zero format differs from sample plates of the time.

Eventual 1942 colours used on this 1941 prototype.

Made of VERY thin metal... you'd have to hold it to believe it!

Powder blue on glossy beige.

Interesting green background.

Military plates went brown after this test, and had the year removed.

Navy blue on cream white... eventually used in '49, '51 and '54.

Same as previous... bare metal on rear. This one was sprayed, not dipped.

Beige background, and no dot divider.

Zero dies misaligned and re-punched. Numbers look strange up top.

First red diplomatic plates came out in 1959, using this same shade of red.

First multi-year experiment. Border debuted in '62.

Circular holes, unpainted rear. Probably a test by the die maker before dies were shipped to Ont.

Colours reversed. Likely an equipment test only.

Yellow quarterly fed through the press as a test. No paint on numbers.

Ontario played with the slogan and its placement before making changes.

Bare galvanized metal, no holes. Probably a die test.

Aluminum plates supplied by ALCAN, used later for vanity plates.
