Why is there repetition of the measure words in 一把把小扇子 and 一枚枚邮票? [duplicate]

Question

This is from my 3-rd grade Chinese 语文 book (transcript is here):

秋天的雨，有一盒五彩缤纷的颜料。你看，它把黄色给了银杏树，黄黄的叶子像一把把小扇子，扇哪扇哪，扇走了夏天的炎热。它把红色给了枫树，红红的枫叶像一枚枚邮票，飘哇飘哇，邮来了秋天的凉爽。金黄色是给田野的，看，田野像金色的海洋。橙红色是给果树的，橘子、柿子你挤我碰，争着要人们去摘呢！菊花仙子得到的颜色就更多了，紫红的、淡黄的、雪白的……美丽的菊花在秋雨里频频点头。

Question: Why is there repetition of the measure words in 一把把小扇子 and 一枚枚邮票?

I would guess this is for poetic reasons, but I'm not sure. I've never seen this before.

The use above seems different to the question What is the meaning of "一把把" on "他更是一把把她的书包给枪了过去“？ where it seems only the first 把 is the measure word.

Answer 1

There is a similar question What does the second "幅” mean in the following sentence?

My answer there should be applicable here too.

"一幅幅" in "一幅幅美丽的山水画" mainly means 'one after another'

With the same logic, 一把把小扇子 and 一枚枚邮票 means "one small fan after another" and "one stamp after another" (meaning many fans and many stamps)
