De Vaucouleurs Atlas Description:

This remarkable object has one of the strongest known bars among early-type galaxies galaxies; Fourier intensity terms to m=20 are still significant in this bar. The bar is encircled by a faint but closed inner ring that looks less elliptical than isophotes of the outer disk. Diffuse spiral arms break from each end of the bar and wind nearly 360^o to form an outer pseudoring that on the whole is type R₁^' , except that the arms wind twice as much in azimuth as a more typical R₁^' OLR subclass ring. The B-V color index map shows that the inner ring and the outer arms are slightly bluer in color than their surroundings. The bar shows little color contrast and no evidence of leading dust lanes or nuclear star formation. There is very light patchiness in the inner ring and outer arms. Several of the brighter knots are very blue in the color index map.

From 2D photometric bar/disk/bulge decomposition, Laurikainen, Salo, and Buta (2005) concluded that NGC 1452 has a nonexponential disk in the bar region, similar to NGC 4608 .
