Worldwide possible 52 number images

I'm trying to come up with a list of images that could be recognized internationally to be associated with the numbers 1 through 52.

Below I have a suggested starting list but there are many things that need to be improved.

I have a single question mark by the suggestions that I think could be better.

I have two question marks ?? where I just couldn't think of anything good.

I want the image to not use the English language or any language for phonetic associations.

Associations such as "Five" rhyming with "Hive" would not be appropriate because that relies on the English language.

English and American cultural associations are okay as long as the international community can understand the association of the image to the number.

Below is my starting list. I would appreciate input from any of you as to other ideas for images to represent the numbers. Especially for the rows that have question marks.

1. World trade center (One WTC)
2. Two finger peace sign
3. Tricycle or Martian tripod or Neptune Trident
4. Chair (has four legs) or simply a square
5. Pentagon shape or five fingers spread
6. Hexagon
7. Calendar showing one week ?
8. An octopus
9. A cat (A cat has nine lives)
10. Bowling pins
11. ??
12. A dozen eggs
13. A horseshoe upside down
14. Two weeks on a calendar ?
15. Julius Caesar (Ides of March) or badminton birdie (15 points wins)
16. Candles (movie sixteen candles)
17. ??
18. Golf course flag pole
19. ??
20. ??
21. A bottle of beer (drinking age)
22. A small rifle ?
23. Half of a DNA strand
24. The Sun (marks 24-hour day)
25. a quarter (coin) or a barber pole ("shave and a haircut two bits")
26. Half a brain, half a deck or Marathon runner
27. A bunch of dresses (movie 27 dresses) ?
28. ??
29. ??
30. The Moon
31. Empire State building (built 1931) ?
32. A set of false teeth (humans have 32 teeth)
33. A large 33 RPM LP record
34. Luke Skywalker's land speeder X34
35. ??
36. Yardstick
37. A magician's top hat (thinking of number 37)
38. A pistol or Jayne Mansfield's upper half ?
39. Jack Benny face (always 39 years old) ?
40. Noah's ark (rained 40 days and 40 nights)
41. Japanese zero (attacked Pearl harbor 1941)
42. An observatory or telescope viewing universe (the word "Universe" equates to 42 via The Hitchhiker's Guide to the Galaxy)
43. A shot glass with Licor 43 ?
44. A 4x4 vehicle such as a Jeep or other
45. Old West pistol or plastic spiral insert for 45 RPM record
46. Full DNA strand
47. A banana clip for an AK-47 ?
48. Outline of the 48 states
49. A pan of gold or a gold bar (49ers prospected)

Ai Suggested:
11 - goal posts
14 - Rose for Valentine's Day.
17 - harp, because 17 looks like a harp.
19 - germ face mask to prevent covid-19.
20 - eyeglasses because the number 20 looks like eyeglasses also 20-20 vision.
29 - frog because it leaps and leap year has a month with 29 days

My additional thoughts:
I need simple recognizable images therefore would probably use a soccer ball instead of goal posts to represent the number 11 (goal posts might be confused with the letter H).

2 - Swan because shaped like the number 2.

7 - James Bond (hat tree that he throws his hat on)?

13 - Goalie mask (Jason Friday the 13th).

28 - My wife suggested a bottle of Midol (you can figure it out).

50 - Shiny metal tin can because atomic number for tin is 50 (but tin could be confused with the number 10)? I like hcs's swimming pool idea for 50 but not sure how to have a small icon for that.

6 - a Lump of coal or a diamond (carbon atomic number 6).

50 - party hat (50th anniversary)?
