[Japanese->English] Text on Birthday Card

Hello everyone,

While on vacation in LA recently, I stopped by the Japanese American National Museum (very informative place). In the gift shop they had a rack of greeting cards, and given that my dear mother's birthday is coming up the Happy Birthday card seemed like an interesting thing to give alongside a gift.

 

[This is the company and the card in question.](http://japanwave.us/collections/greetinglife/products/greeting-life-birthday-surprise-change-card-mother) It has a small image on paper on the inside and a strip that if you pull down, causes one image to roll up and the other to be revealed.

 

I also [have a picture](http://imgur.com/n9Q0m1S) of the two images for a bit clearer view of the text.

 

Lastly, I have the actual text. I know a small small amount of Japanese and am familiar enough with the language that I was able to type the text out in attempting to see if I could cobble together a translation on my own. Unfortunately the results are a bit off. Which is why I'm asking for help.

If anyone is able to give me a hand, I would greatly appreciate it. Thanks!
