24L Colorful 1960-70s Number Blocks Kiddie Novelty Buttons 5/58"

This set of five colorful number block novelty shank buttons (showing numbers 1, 2, and 3 in raised, block-style lettering with horizontal line backgrounds for a classic "building block" or toy effect) are square-shaped and come in bright primary colors: one yellow, two green, one orange, another green, and one red.

Measure approximately 24L, 24 lignes, 15.2 mm, and 19/32. (close to 5/8").

They were made in the 1960s to 1970s, during the height of playful molded plastic novelty buttons for children's clothing. This era saw a surge in educational/toy-inspired motifs (like ABCs, numbers, or building blocks) on baby/toddler rompers, play outfits, learning-themed apparel, or nursery items—reflecting the post-war focus on colorful, fun, and subtly developmental designs for kids.

The simple square molding, raised numerals with line details, vibrant solid colors, and integral self-shank (molded plastic loop) are indicators of 1960s-1970s novelties with bold colors for visual pop.

The material is molded plastic, a durable thermoplastic (likely acetate, early acrylic, or polyester resin common by the 1960s-1970s.

These were produced in the United States, where manufacturers created abundant educational kiddie novelties during the baby boom and early learning toy craze. Number/block motifs tie into classic children's toys like wooden alphabet blocks, making them nostalgic favorites for preschool or counting themes.

A bright, educational gem—perfect for counting-themed vintage collections or baby-themed crafts!
