This is a Gibson wedding anniversary greeting card, and its style and markings place it in the early–mid 1940s, roughly circa 1942–1946.

Here’s how we can date it:

1. Gibson Cincinnati imprint

The back shows:

“GIBSON CINTI., U.S.A.”

Gibson used this specific Cincinnati imprint format primarily in the late 1930s through mid-1940s. Later cards usually say “Gibson Greeting Cards” with fuller corporate styling.

2. Artwork & typography style

The dancing couple illustration, soft pastel palette, and playful mid-century script are classic WWII-era Gibson design. The netted drapery corners and cartoon-style figures are especially typical of the early 1940s.

3. Paper stock & printing

The slightly textured, cream-colored card stock and flat litho printing are consistent with wartime and immediate post-war production.

4. Message phrasing

“Regular gal and guy” and “feeling spry” are slang expressions that show up heavily in 1940s popular culture, especially during and just after WWII.

Best estimate:

👉 Circa 1943–1946 (most likely around 1944–1945)
