I've shown this calligraphy last week on my blog. It's so fitting to my blog that I better give a full explanation.
My wife thought of the words and had it made for me after seeing how much time and energy I devote to tea. The 4 main characters are (from top to down and then right to left): Cha Qu Wu Qiung (pronounce: Tcha Tchü Ou Tchiong - word by word: Tea interest none limit).
Sencha de Shimizu, Oku-yutaka
