He is well-known for his artworks that gained popularity among the masses through book covers, stories, cartoons, calendars and illustrations, especially in the Deepavali magazine.

The combination of Kanekar's imagination and the caricatures of Dalal took a gibe on the political policies and the tyranny of the British Raj.

In the same year, he started Dalal Art Studio in a small room under the stairs of Mauj Publishing House.

Due to the gradual expansion of his work, the studio later relocated to a larger space near Kennedy Bridge in Mumbai in 1944.

[5] Along with Roy Kinikar, Dalal started publishing the annual Diwali magazine titled Deepavali in 1945, which was in Marathi.

Dalal and Kinikar deliberated carefully about the selection of literature, reviews, letters from readers, advertisements, stories, font layout, designs, color scheme, blocks, printing etc.

[6] Articles from renowned writers like V. S. Khandekar, P. B. Bhave, Vijay Tendulkar, P. L. Deshpande to newcomers were published in Deepavali.

Some special features of the publication included a colorful series by Dalal based on Indian Sanskrit literature such as Ragaraginya (Raga-Ragini), Barahmasa, Ritu, Nadya (Rivers), Navarasa and Sringara Nayika.

[3] Dalal created advertisements and calendars for companies like Dongre Balamrut, Kota Tiles, Dhootpapeshwar, Vartaki Tapkir, Kokuyo Camlin, Kirloskar Oil Engines.

Plays like Ithe Oshalla Mrityu, Lekure Udand Jahli, Matsyagandha, Natasamrat were produced during his time and he was involved in set design along with the art direction.

His personality was polite, hospitable and transparent which made the publishers, editors and fellow artists feel at home with him.

He had painted the portraits of a number of famous personalities, including Mahatma Gandhi, Jawaharlal Nehru and Vinoba Bhave.

His paintings were varied, such as the sketches that seem to come alive with the flowing lines of the novel Bangarwadi or the black & white illustrations in the book Raja Shivchtrapati written by Babasaheb Purandare, which is a classic collection in itself.

"[11] Dalal had studied Indian miniature paintings, including the Jain and Rajput styles during his time in the Bombay School of Art.

He also focused on the techniques, color schemes, compositions, shapes of Indian books, manuscripts and murals at Ajanta and Ellora Caves.

Indian painters like Raja Ravi Varma, Amrita Sher-Gil, Abanindranath Tagore, S. L. Haldankar, Raghuvir Chimulkar, N. S. Bendre were his inspiration.

Dalal also studied the art of European Western artists such as Vincent van Gogh, Rembrandt, Constable, and J. M. W.

[13] In December 2015 through January 2016, a retrospective exhibition was held at the Nehru Planetarium, Mumbai, to commemorate Dalal's birth centenary year.
