Vintage Hallmark Bridge Score Pads Spiral Bound--TWO sets of TWO 30-page pads

Description

Two sets of vintage Hallmark Bridge Score Pads. Spiral bound at the top. Two pads per design: Pink Cascading flowers and Yellow Roses (
my names
, as a way to decribe them--photo 1).
I can't decide if the logo is the 1952-1977 one, or the 1977 to present day. The image is small, so it's hard to discern the subtle difference with the balls at the top of the crown points. (photos 2, 10. & 11) These were from my mother, but she never played bridge, so I can't imagine they are post-1977. it's possible they came from her mother (who died in 1958), or they could have a different origin. Spiral binding first started in 1932, so that doesn't narrow the date. Other pads I've seen dating from the 1970s did NOT have spiral bindings, but I can't find anything to find out when they fell out of fashion for score pads.
I am selling them "as is" and cannot place the date more precisely. If that really matters to you, then maybe you should look elsewhere.
The paper has darkened with age.
There is no date printed anywhere on the pads, though it looks like the price was 25 cents per pad.
The style and size is the same for both sets. The paper size is 3 1/4" x 6 1/2". The inside front cover has a summary of the scoring rules (photos 5, 6, & 7), though the layout is a little different for each set. The front and back covers of each pad seem securely attached, as do the sheets.
All 4 pads have 30 sheets. It's possible they were never used. The scoring columns are printed only on the front of each sheet. (photos 5 & 8)
The Pink Cascading flowers (photo 3) have different product codes: one is  25EPA 2-5, the other is 25PA 20-2. The pads appear identical, so I have no explantion.
The Yellow Roses design (photo 4) has a code of 25PA 23-3 on both pads. I could find no information about any of the codes.
There's a small smudge of something on the front of one of the Pink Cascading pads, just under the "D" (photos 9 & 7). I don't know what it is/was.
Please inspect all photos carefully, use the enlarging feature, and ask any questions before bidding.
