Cryptic crossword No 3,450

Some real gems in here with nice surfaces. 23d was particularly nice, and I liked 11a too. 1d was cunning :)

Fun succinct surfaces, many raising a smile (23d!) and clever constructions although I found I needed to check a couple in the SW corner but overall very enjoyable. Top picks 23d, 9a, 2d, 4d, 22d, thank you
