It is a Showa retro flower brush 昭和レトロ系の花のブラシです
I made it roughly, but

If you combine it with retro-like letters and pictures, it may look like that ...

You may not want to make the ribbon brush too thin.

If you change the size of the flicker brush and draw it crunchy
You may have an atmosphere like Showa tableware and cooking utensils.

The pattern is simple, so it's a bonus ^^;
ざっくり作ったものですが 

レトロっぽい文字や絵と合わせるとそれらしくなるかも…

リボンブラシは あまり細くしない方がいいかもしれません

ちらすブラシは大きさを変えてザクザク描くと
昭和の食器や調理具っぽい雰囲気がでるかも

パターンはシンプルなのでおまけです^^;
